Information
At Cosmic Waters Rattery, our breeding program is built on intention, ethics, and deep respect for the rats in our care. Every rat in our program is carefully selected and raised with a focus on health, temperament, structure, and lifelong well-being.
We do not breed for quantity or trends. Each pairing is thoughtfully planned to improve our lines while preserving gentle, confident personalities and strong foundations. Our rats are handled regularly, raised in enriched environments, and observed as individuals — because who they are matters just as much as how they look.
Our Breeding Program
Our program focuses on:
Temperament-first breeding (calm, social, people-oriented rats)
Health-conscious pairings with careful line consideration
Strong structure and longevity
Early socialization and enrichment
Ethical placement and lifetime responsibility
Rats in our program are never treated as inventory. Each one plays a role in the future of our lines and is valued for their unique personality and contribution.

Our Promise
We are committed to transparency, education, and support. Whether you are an adopter, fellow breeder, or simply learning, we believe responsible breeding starts with honesty and ends with lifelong accountability.
Every rat bred by Cosmic Waters will always have a place to return to — because responsibility doesn’t stop at placement.
