Took some pics of just Mom and mom with her baby too. So you can see what the babies will look like as adults. Siamese babies don't start off with points. And you can see as adults they don't get that large still! Not much bigger than the babies now.

My application will drop March 23rd. I have mostly girls available and 3 boys.

They got separated by s*x today with the baby boys going in with the adult boys.

Celebrating 10 years since I first began breeding today!

I can't believe 10 years have gone by!

My first breeding rat was a Siamese dumbo girl named Khaleesi who was the best rat ever.

I still have her line going great with my Siamese Dwarfs.

Thank you everyone for your support and in sharing my love of rats these 10 years!

I love using wheels for my dwarfs. They are prone to weight gain and running can help. The girls especially love it!

This is my favorite wheel choice. I use for my dwarfs and my hamster too! Size Large. It's as quiet as a wheel can be.

Our Story

We focus on healthy beautiful rats with amazing temperaments!

Our passion is color points, with a focus on Dumbo Siamese, in Standard Size and Dwarf. We breed several different lines and varieties though, including:

Black, Russian Blue, Blue, Russian Silver Burmese, Sable Burmese Tonkinese Black Eyed Siamese Marten Spotted Tabby (Marble) D’Argent (Silvermane) BEW Roan Frost Variegated, Blaze, Self/Unmarked, Irish Standard Coat, Harleys, Velveteen and Harley-Velveteen Dwarfs & Standard Size

Almost all of our rats are Dumbo eared, but we do sometimes have standard ear.
