Website Updated 7.2.2022


We do have babies! But we are closing in on the last part of the breeding season in the USA, as rats fertility drops in the heat. So if you do not adopt now, you will miss out until the fall.
Join the mailer to get notified on future litters!

Please excuse the mess at our house in the front yard. We are landscaping.


Our Individual Lines

This page is updated every time we post a new litter to keep the info current for our adopters.

Let me make something very clear before you read about our lines. All of our wonderful adopters are under contract to update us on any concerns they have with their rats such as temperament issues and eventual date of death. This is so important to us because we can't breed healthy animals without knowing what each individual animal we breed is doing health and temperament wise. So if in the event there are issues with any of our lines we take that very, very seriously. We keep this info in our database to determine if specific lines should continue to be bred or not. If things are not looking good, and there are complaints about temperament or the rats aren't living as long as we think they should we have absolutely no problem ending a line. We will even let our adopters know we ended it, and tell them the reason we did it. This is just what good breeders should do. We cannot in good conscience adopt out questionable animals. So having said that the lines on this page might change. This is to better our animals.

American Blues

Beautiful super dark American Blues are my main specialty. I have been breeding this line of them since 2004. I started this line myself. My American Blues are very long lived and have excellent type. They are on the beefy, large and blocky side. Just like I like them!  They are very sweet and loving! I just adore their mellow temperaments! My American Blues are all from the same rat in my logo. Mary Jane. I have worked on this line longer than any of my other lines.

They have been bred into my new Hairless line from Nebraska and into my Marten line. So my Blues are coming out of those lines as well.

I have shipped this line to France as of 12-9-2013.

Dr. Fitzgerald has complimented me on this lines health, beauty and coat quality. Just before I exported them to France.

Russian Blues

altMy Russian Blue line has been with me since 2005. I had gotten them from a local breeder and they trace back to the SRR lines. This is a very strong long lived line. And they are of great type and on the larger side. They are very mellow and lovable!

Right now my RB do not carry ANY colors at all. They are a true representation of the color. Which is something you just don't see anymore. Most are muddied up with mink and or other colors.

This line has perfectly lovely and mellow temperaments and great longevity.


My Burmese are exquisite to say the least.  And they get a lot of attention for it. Even Dr. Fitzgerald form the emergency vets show on Animal Planet has complimented me on their beauty as far as coats and their health when I exported them to France.  They are my pride and joy. These were imported by Connie Perez import to the US. I got mine right from her. And they are very large and long lived with excellent type. They also have super sweet loving personalities.

I do color breed the Burmese as I do with all my lines. So all you will see here is black and agouti base! Most are Sable and all are my special Rex or Double Rex gene! 

I have shipped one of my dwarf Wheatens to France as of 12-9-2013. Along with 4 other rats one of which was  a dwarf Black. And these are the 1st dwarf rats on in that country. Alexia of Citron rattery is who I exported to.

This line has excellent temperaments and great longevity. They are huge rats and are couch potatoes. I am very, very proud of them. I have bred them for many generations.


Black Eyed Siamese

My Siamese are all bred for Black Eye. I do not like them to be carrying ruby eye as that dilutes their points. They are medium sized rats with very loving personalities.

My line comes form the same 100% pure UK rats I received from Connie Perez. So they have the same long life spans, type and size. They are also Rex in most cases or standard fur. I had out crossed them with my Russian Blues to add that color into the line. So all if not most of them are RB point.

This line has perfectly lovely temperaments and great longevity. they are huge rats and couch potatoes.



Our Silvermane line was imported from Exotic Whiskers Rattery in Canada as a co-shipment between myself and Emerald City Rattery in March of 2016. And are the 1st ever of their variety in Colorado.

Silvermane is new to the world. It was discovered by Squeaks and Nibbles Rattery in North Carolina in 2012. She named them Silvermane and we opted to keep that name out of respect for Squeaks and Nibbles even though AFRMA choose a different name later on.

Silvermane rats have a mixture of Silver hairs and their natural body color. They have very, very soft coats.

Our line has a very sweet, and very curious disposition. They are the 1st at the door to greet you. And they have a lot of energy to play.

So far this line has had zero issues with health or temperament.



My Hooded are an old line of mine. I have been working on them forever. I have now bred my Marten and Fuzzy Hairless into them. So this line is super sweet, long lived and very beautiful. I cannot say enough about this line. I just love them.

Harlan Dark Agouti (From Harlan Labs)

Here in the USA we have very pale Agouti rats. Unlike the ones in the UK. And I would say this line represents the UK coloration to my eye. They are many shades darker than the Agouti found in the USA. This pic shows a Dark Agouti next to a regular Agouti.

This line is straight out of the Harlan laboratories. I have out crossed it with my guys now to get the Dumbo gene in there. But the color is a Harlan Patent. From their Dark Agouti line. When I got it from Isbn rattery who got it from the lab for me they were part Sprague Dawley and  part Harlan Dark Agouti. They came with 11 thousand generations of pedigree, DNA mapping and health info. What more can you ask for? Longevity? Yes they have that too. And there are no health issues in the lines as per their lab paperwork. I am hoping to order more Harlan lab rats in the years to come as my husband now works at the lab that ISBN got my line from. I would like to put in an order for some Wistar Hans!

As of 2016 I have finally decided to breed them directly into my main lines. They are no longer in the testing phase in my rattery. It took me years to get to this point. Currently, I am adding colors into them to make Dark Agouti Cinnamons, Russian Blue Dark Agouti, American Blue Dark Agouti. They are now integrated into my Black line, which is a line carrying nothing at all to use as an out cross in all of my lines.

I have allowed 2 other breeders to work with this gene. This line is very sweet and loveable!


My 24k Gold Line (Harlan Dark Agouti Fawns)

These are from the Harlan Dark Agouti line. You cannot get these but with myself and or 1 other breeder I have sent the gene too. No one else is breeding from the Harlan DA rats. This is a very special color. Much more brilliantly colored than regular Fawn. 

They are very brilliantly colored. No there is no photo filter. This is true to life color showing in the picture.

They are very very sweet, mellow loving rats who love people. They are very nice type and are larger rats. Nice blunt noses.



Our Marten line was imported from Exotic Whiskers Rattery in Canada as a co-shipment between myself and Emerald City Rattery in March of 2016. And are the 1st of their variety ever in Colorado.

We have both the Black Eyed and pink Eyed types. But we prefer the pink ones.

So far this line has had zero issues with health or temperament. They are now considered our line, as we have had them for lots of generations and do represent Camarattery. They are very mellow rats with great health. We have never had a complaint about them. And we are very proud of them.

My oldest line of American Blues are outcrossed in this line.



I was one of the 1st breeders to get the Dwarf gene. And my Dwarf are some of the most established in the world. Our Dwarf are more robust, not overweight and represent the standard rats in their line. They are of excellent quality and temperament.

Dwarf have more energy! So consider that. So don't just buy them for a little kid that can't handle that. They are also faster. And they need a larger cage not a smaller one because they love to move around more than standard rats. Do not purchase them and put them in smaller cages.

Dwarf are small so they have small litters. They breed at an older age than standards and because of these 2 facts they breed very slow. Do not assume you can just get a pair of them at the same time. It may be years in between the time I post one for adoption then post another.

Our Dwarf were the 1st Dwarf ever to be imported into Europe.



The Whiteside gene was rediscovered by Emerald City Rattery. And all of mine are directly from her. This line has been worked with longer than any other Whiteside line and is very, very sweet. I have nothing but positive things to say about them. They are of good size, and great temperament. They are very beautiful too. This line has quite a bit of the blood from my black line in it. As I have out crossed them to that line a lot.  Their genetics are almost all Camarattery blood now. We have bred them for many generations. So they are one of our older lines.

This line has perfectly lovely temperaments and great longevity. We have never had any problems with health in this line.


Albino and Ivory

My Albinos came out of my Hooded, Blacks & Hairless. They are very sweet, very soft and perfect pets. They are very, very white and have wonderful temperaments. They are a bit more energetic and curious. So they want to know about everything. I use this line to out cross my Hairless so most of them carry Hairless.



altHarley are Long Haired rats. My Harlay came from Emerald City Rattery who imported them from Georgian Bay Rattery in Canada.  And she outcrossed those with my black line and my fawn line. She did a ton of work on these.

Harley can have scabs, poor greasy fur quality, and ear infections and lactating problems. So making them healthy is a LOT of work! And a lot of outcrossing to healthy lines. Many breeders are not out crossing, but cementing the issues with inbreeding.

I do not reccomend keeping Harley on any type of wood bedding as this seems to irritate their skin. I reccomend a paper or paper pellet bedding. This will keep their coats looking good. Also they do not do well on high protein diets. This causes scabby skin. Keep them at 14% protein.

This line has been bred for several generations to get their health looking good. They are more expensive because of that. And because we have to keep a larger number of them to find the best ones for breeding, that costs more to feed, cage and enrich them. Instead of posting them as 5 weeks old like other lines, I do keep this line longer to be sure they are of the best quality for us and our adopters.

Right now this line is doing really well. Coats are looking good, health is good and temperament is a bit energetic. I don't reccomend them for small kids right now because they don't hold still. I will have both Harley and standard hair in most of my litters because of outcrossing to new blood. So I do not have a ton of actual Harley to offer up.



Angora is a brand new mutation. So not much is known. There are only 6 generations of them. Its genetically a Harley but it's also a recessive curly that only pops up on Harley, and has a different feel to the coat. It's the softest coat type. It's so soft you almost can't feel it.

The gene was mutated at Pixie's Rattery in Canada and she shipped them to me I was the 1st in the USA to get them. It was thought by Pixie that the curl may come from a Satin gene she has in the line. But she wasn't sure. So she sent them to me to work on and figure out. It was thought that Satin was in the line. However from the breeding's I have done and the ones done by RuBY Rattery, we have discovered that there is no Satin's popping up in our litters. So the gene simply isn't present. Even if we breed and Angora to a standard rat carrying no other coat genes, and breed those Angora carriers together, there is never any Satin there. Its only Angora and Standard coated babies.

Angora will not be sold to general adopters for quite a while. As that has no benefit to the variety whatsoever. But we have now shipped it to another as well so the 3 of us can work on it together.

At this time we have ended the line from Pixie, there were far too many health issues. They were getting rottonous mouth infections and terrible rotten teeth and failure to thrive. They were also getting rotten infected nipples on breeding females.

The Angora gene also popped up in our Harley from Georgian Bay Rattery in Canada, which is somewhat of the same pedigree as Pixies, with some differences. So we are just working with that line now to see if its healthier. So far is has about the same issues as Harley rats. But at this time in their evolution they are scrawnier than they need to be. You can always tell n Angora in a litter by its size. They also have their own unique whisker type.  As babies they may or may not have some curl to their fur. But as they age they get curlier. Better ones curl earlier. As far as their health, they reflect our Harley line. Which are doing very well. However they can be a bit scrawny as babies. That needs to be fixed. All Harley and Standard hair in the Angora litters have great health. This line is a bit more energetic so I do not recommend them for smaller kids.

I do not recommend keeping Angor on any type of wood bedding as this seems to irritate their skin. I recommend a paper or paper pellet bedding. This will keep their coats looking good. Also they do not do well on high protein diets. This causes scabby skin. Keep them at 14% protein.

This line has been bred for several generations to get their health looking good. They are more expensive because of that. And because we have to keep a larger number of them to find the best ones for breeding, that costs more to feed, cage and enrich them. Instead of posting them as 5 weeks old like other lines, I do keep this line longer to be sure they are of the best quality for us and our adopters.



Marbles are very new to the fancy. They came from New England Reptile Distributors (NERD) in New Hampshire.

Not a lot is known about the longevity of the line since it's so new. But what is known is that they have problems with the teeth mis-alining and crumbling and Crypt Orchid. The CO being an issue with the testicals not dropping and one or 2 of them staying in the stomach area. This is a recessive gene. By 5 weeks old when the babies go home this is already known, and I will not allow CO babies to be adopted out, should it arise in my breeding's since rats who have this are likely to develop cancer. But please note that while I will not breed from rats with tooth issues or Crypt Orchid. However, I cannot control the tooth issues from arising as the rats age. This may be an issue that arises if you adopt Marbles. Right away I will be heavily out crossing this line with my very old healthy lines to improve the Marbles. So go into it knowing that. Please note that the non Marbles in the same litters do not have the tooth issues. This seems to only develop on the Marbles rats. And we have never had a single CO rat in this line ever. Not in our rattery.

It looks similar to the dominant Merle gene, except that Marble is a dominant gene that works on all other colors. Not just Mink based rats like the Merle. The Marble rat has Black splotches on it. And it has a dorsal stripe.

 My particular line was imported from Georgian Bay Rattery in Canada. And I have seen tooth issues in this line so far. The 1st litter I had only 2 did not have tooth issues the rest did. Note for adopters the Marbles have tooth issues, the non Marbles in the same litters are not at risk of having the tooth problems. It's only the Marbles themselves.

I am currently out crossing this line with my Whitesides or Self's who have a strong and healthy pedigree. 

So far this line since I have out crossed it has very, sweet and playful temperaments. They seem very mellow too. And they are larger rats. At this point this line is more than 3/4 my Whiteside lines blood. So health and temperament is very good right now. No tooth issues in the past 2 generations as of 12/2021. So that is good!



altThe Chocolate line I have was Imported from Pixies Pocket Pets in Canada to Emerald City Rattery, she then shipped one to me.

I have out crossed them to my black line and Albino line and Siamese line.

I have been happy with their overall type. Shape is very good. No health issues have been seen.

11.2020: This line is where I want it temperament wise. They are now calm. This current generation is gen 7 for me. And that is when I call them my own.

2021 will be the year of Chocolates. I will be making most varieties I have in a Chocolate option. So you will start to see me using a Chocolate parent in many of my litters to get that going right now.

5.7.2022: I am at my 7th generation with this line. That is when I finally call them my own line. Their temperaments are very calm and squishy. Never a single health issue thus far. So I will be keeping them in my breeding program. They are exactly what I am looking for.



altThe High White markings on this line come from my old Chinchilla line that I got from Canada. I no longer breed the Chinchillas as I found it boring. This line I have bred for around 4 generations. And I didn't get a lot of pedigree for them. So I am having to build it myself from my own breeding's and start from what I know. I am out crossing them to my Russian Blue line to add good temperament and longevity as I do not have a ton of info on these. The Overo patterned rat was named after the Overo horse with very similar markings and similar colon issues as babies. Lethal High White marked rats can get megacolon as babies right after they start eating solid foods. I keep this line longer to make sure I am not sending home babies too young as they are free and clear after they are able to pass food through the colon. So I let them go home around 7-8 weeks old instead of the normal 5 weeks I usually do.



Fuzzy Hairless - OLD LINE -

My Hairless gene came from Emerald City Rattery (RuBY). They have been out crossed from my Albino & Marten lines. This line has a bit of fuzz on them until they are full grown adults when they lose much of the fuzz. They are very mellow and melt in your hand like butter. This line has great longevity and have very mellow temperaments. They are larger rats and have long life expectancy. I am very proud of this line. They are just wonderful rats and love everyone. They are a little bit more expensive because of the work that goes into them. And they are harder to find. 

This is not a new line for me. I just put them down at the bottom of the page with the new rats so they are next to the bald Hairless to show you how differently they look next to each other. This is one of my older lines I have worked with for many generations, and does represent Camarattery.

Hairless - New Line

This line is new to us as of the Summer of 2020 and do not represent Camarattery or our lines. As we have not had a chance to call the line our own yet. Right now we are testing their health and evaluating them overall. I can say that I am very impressed with their temperaments. They are from FVR rattery in Nebraska.

  • Generation 1 - We bred them together. And did adopt out babies. They are not as calm as our lines but they did pretty good.
  • Generation 2 -  We have out crossed them with our Marten and American Blue lines to add all of the good qualities those lines have to offer. Those babies did get adopted out. And are a bit mellower than the previous generation. I had about 3 litters this generation.

Homozygous Lethal Dalmation - New Line

This line was shipped in during the Summer of 2020. They are super cute! Not as large as babies for sure. A little more on the fragile side. They take a while to catch up in size. I will be working to change that because I like bigger rats. They carry Russian Blue. Their markings really are fantastic. 

This line is new to us as of the Summer of 2020 and do not represent Camarattery or our lines. As we have not had a chance to call the line our own yet. Right now we are testing their health and evaluating them overall.

For the non genetics expert the reason they are called homozygous lethal is because if you breed 2 of them together, and while in utero if babies get this Dalmatian gene from both parents the babies will die before they are born. There are several rat types that do this. Pearl and Marble do the same. So you get better results by only breeding one dal not 2 together. 

  • These are smaller rats. They are smarter and have more energy. They grow and develop slower.
  • Generation 1 - I did adopt out a few. They are smaller than my rats as babies for sure. Not as mellow as our lines but not too bad.
  • Generation 2, 11.2021 Mellower than generation 1. Finally getting Dumbo's. The type has improved. Patterns are pretty. Babies are still growing slower, so they are littler at the same age as my other other rats of their age.

Tonkinese - New Line

I shipped this line here in the Summer of 2020. They do carry Russian Blue and possibly American Blue. I do not know much about their current genetic temperaments. Tonkinese are the same as the red eyed Burmese that have been popping up in our litters since 2009. All Tonkinese are originally from Camarattery lines. We shared them with other breeders shortly thereafter in 2009. Back then Red Eyes on a Burmese was not a desirable trait and they were pet homed for the most part. But other ratteries did get them from Camarattery directly. Because show standards asked for Black Eyed we did not keep them here. At that time our lines went to a breeder in TX who later quit breeding and took them to a pet shop at which point a newer breeder grabbed them thinking it was a totally new gene and named them Tonkinese and called it a new variety since we think they didn't know it had already been around for many years. AFRMA has decided to name them Siamese Sable. And there are talks of it becoming standardized. It may not have been a desirable trait for show standards in years past but now people like the Red Eyed so it's being bred often now. I sent some of these gen 1 babies to 2 other breeders to work with. They can help me with them.

This particular line is new to us as of the Summer of 2020 and do not represent Camarattery or our lines. Even though way back in the pedigree it is our blood. Right now we are testing their health and evaluating them overall.

  • Generation 1 - A few seemed mellow but some were not. I did adopt this generation out.
  • Generation 2. I only got one Tonk. I kept her.
  • Brought back some Tonks that are all Dumbo from one of the other breeders I shared with on generation one with, to add more diverse blood into mine. Also those are all Dumbo. Some of my UK Rex gene was bred in. And Satin popped up out of the Tonks so I now have that.

Golden Black Eyed Siamese - New Line

This line I shipped in during the 2020 Summer season. They are rats of great type, do not carry dilutes, and do carry satin and Harley. I do not know much about their genetic temperaments.

This line is new to us as of the Summer of 2020 and do not represent Camarattery or our lines. As we have not had a chance to call the line our own yet. Right now we are testing their health and evaluating them overall.

  • Generation 1 -  We kept them all to evaluate them. They are nervous.
  • Generation 2 - We have decided to keep all of them as well. They are nervous of people.
  • Litter 3 Gen 2 out cross. I bred one of the Goldens to a Velveteen from RuBY rattery in the Springs. She brought those in from NY. Already the babies are calmer! No skittishness, no biting like previously. They let you hold them. And don't try to get away. Huge improvement!

Pearl & Merle - New Line

Our Pearl Merles are brand new for us. We have no time put into them at all. So we are still evaluating them. We just got them in the Summer of 2020. This is a UK Pearl and Merle. They come from Karen Robins the President of the American Fancy Rat and Mouse Association, they had one outcross to add the Merle gene when I got them. So they are very well pedigreed and worked with. This is a show line. I cannot tell you how they will be in the long run because I just don't know them. As soon as I know more I will update this info.

  • Generation 1 - We already have some Dumbo babies. We have out crossed them with one of our Harlan Dark Agouti in the Whiteside line.
  • Generation 2 - 8.15.2021 - All Dumbo this time. Temperaments seem very good this generation. We used a Dwarf male from our old Whiteside lines as the father to this generation. So these are 3/4 Camarattery Blooded.

Recessive Patchwork - New Line

Patchwork have been around longer than I have been breeding. But the gene was lost for a short time and resurfaced. There are not many of them anymore so they are considered rare. 

They constantly lose their hair and grow it back in a new unique pattern. Some breeders call them Rorschach rats because of this. Which we think is a fitting name as well. 

We got this line from another breeder.  So far their temperaments have been great. No problems there. The breeder I got them from said she could only get 2 real PW to survive. Others would wean then die or die as infants. There were Patchwork babies with eye issues as well. She sent me the 2 survivors and some carriers. She did not have a chance to out cross them from the previous breeder. So she only had one generation. The previous generations to hers were not bred for health at all, they were very poorly bred out of feeder lines. And mixed with everything imaginable. Including other problematic lines to compound bad health. Most faired poorly as a result. And we are going to work hard on fixing the issues. We will be breeding all of their old blood out of this line quickly.

I have sent them to 2 other breeders that I work closely with so that we can further this line more quickly and out cross them to good blood faster. We are now able to send this line back and forth to each other for out crosses so that they re not too closely related.

  • Generation 1 - We saw a few Dumbo's in the standard hair babies in the litters. We did adopt out a few that survived. They are not as mellow as our lines but they are not bad. A few died after weaning or birth. We sent several to a breeder we work with for out crossing at her rattery.
  • Generation 2 - 1.1.2021 These are out crossed one time with Camarattery lines. These are all Dumbo. We are adopting out a few. These are a little bit mellower than generation one. Some died as infants. Some  of this generation from the other breeder I sent to went to a 3rd breeder we work with for out crossing. Not getting a lot of actual PW. Just carriers.
  • Gen 3, lost several after before and after weaning. But they type is better. Eyes are better on some. One has survived and we are going to use him in our breeding program. Most are not born PW I keep getting carriers and not actual PW. That is frustrating.
  • Gen 4. So far all have lived! These are very heavily out crossed with our lines. Eyes are perfect! All are Dumbo! 3 litters have been bred to our lines for out crossing. Those are carriers. More on gen 4...We have brought a carrier of the out crosses from the 1st breeder we sent these to on gen 1 back. To bring in new blood. I will see how she does for us and see how those out crosses are fairing.
    Generation 4. Outcross from our lines from another breeder.
  • Gen 5 Outcross to our black line again. They are mostly our blood now. Temperaments have been fantastic. No tumors in the line as of yet. None of the standard haired rats in the litters have had any issues. As they are not Patchworks there was no PW issues to be expected anyway. They all seem like larger rats as well, with very mellow temperaments.  I am starting to become more pleased with the Patchwork individuals from this line over all.
