Edit: 3/4 girls have found a home. The little hooded silvermane is all who is left.

I have 4 girls looking for a new 🏠

The older girl is between 6-8 months old. And the younger rats are from a recent previous litter.

All are very sweet (and use to dogs lol).

Please inquire if interested

We should have 3 litters born soon! I’m so excited for these babies, they are going to be excellent, friendly pets.

I’ve taken the time to reflect on my breeding program, and while I love flashy colors and excellent type in my animals, I’ve decided to take a few steps back and focus purely on temperament with this group of animals- and so far I am blown away with the progress I’ve made in such a short amount of time.

My current group of animals come from a couple different ratteries (and of course my very old line is being continued as well within these lines), and so far every rat I’ve paired has complemented the other in such a way that the offspring take the best traits of both parents and are such happy go lucky little creatures.

My rattery website is still under construction, but I am updating bits and pieces here and there. I’ll be posting my litters up on my website for those of you who are wanting babies and I work on a first come first serve (you must still be approved) bases.

Previous adopters do not need to fill out another application.

I have 4 girls paired to a really nice rex chocolate boy 🍫

All of these rats have fantastic personalities, so I’m very excited for these litters.

Babies from these litters WILL be available for adoption!

More to come 🙂

Edit: the girls have found a home

I have 3 girls 👀 🏠

First girl is the black girl with the cool white spot on her shoulder. She is the mom to the other two.

Then we have the two little Russian blue girls- one with the head spot and the only other Russian blue baby in the picture. The babies are now 5 weeks old.

All are friendly

That part of the line is being discontinued due to momma rat being unable to lactate. Most of the litter was lost and the last two babies were fostered to another rat.

There is no fee.

There is a contract/waiver.

Please send me a DM if interested and I will go more in depth about these girls.

Our last litter for the moment was born a few days ago! Another dwarf carrier litter!

I might have some babies available after all 🙂 I’ll be sending testing in again next week so we will see. I’ll have both males and females available BUT not very many. I will post when my website is updated and I will accept applications then.

Please understand that while I love working with other breeders, I am currently not adopting out to them.
