About Me

Welcome to Perfect Storm Rattery. My name is Hannah Darrow and I am the practice manager and lead Registered Veterinary Technician at Santa Rosa Veterinary Hospital here in beautiful Santa Rosa California. My pet rat journey began as an animal-loving kid who couldn’t have a dog. I gained a sense of pride because the rats’ wellbeing was my responsibility. Now, a few decades later, my love for pet rats still runs deep. After sustaining a hand injury, I shifted my entrepreneurial energy from my successful dog training business to raising Mycoplasma Pulmonis-free rats. And I’m having so much fun!  

Our focus at Perfect Storm Rattery is to breed healthy, friendly rats and to make these bundles of joy more accessible to kind owners. During these socially distant times, we are grateful to provide people with pets who are super-social, family oriented and offer sweet, silly companionship.

"Ariel" litter, born of Dalton and Duke 12/5/2020

Dalton is a petite, glossy black berkshire rat with dumbo ears and a standard coat. Duke was a busy boy this fall and fathered both of my current litters. His cuddly personality and unique rex coat always yield fantastic kittens. 

Mulan and Ariel litter update 12/28/20

Lego and Dalton are gentle, bonded sisters and decided to co-parent their litters this go-around. At first they made separate nests but soon decided to share nursing and napping duties and it has been a joy to watch. Their kittens are exceptionally sweet and interested in human contact. Although we did not get a ton of facial markings this time, we did get a wide variety of stunning rex and standard agouti coats and majority dumbo ears.

About The Rattery 

Our AFRMA rattery is based out of my home and is a labor of love. Each litter is hand raised by my rattery partner and myself.  Our kittens are best known for having incredibly "human-centric" personalities.  They enjoy being handled and are trained to use litter boxes from a young age.

We DNA test every breeding pair multiple times throughout the year to guarantee our rattery remains free of Mycoplasma Pulmonis (the most common respiratory disease in pet rats).  We believe rats deserve a high quality of life, free from constant sneezing!  Our radiographic diagnostic procedures are trauma-free so we can ensure the rats are healthy without sacrificing their comfort.  

This website is updated regularly with test results, litter updates and planned breedings so check back often!
