The Breeder

About Tay

Hi — I'm Tay. I'm 30 and my love for rats began at age six when I got my first pet. Rats have been part of my life on and off since then, and in my early twenties I began researching breeding with the goal of improving rat health, temperament, and reputation as pets.

My priority is healthy, happy rats and a positive experience for adopters — especially first-time owners. I offer lifelong mentorship for every rat adopted from Daisy Fields and aim to build stronger relationships with adopters, new breeders, and the broader rat community.

Our Approach

Temperament & Socialization

I focus on improving temperament through a sound genetic base and positive human interactions. Every rat is temperament-tested to make sure adopters receive friendly, curious companions. I believe thoughtful selection and early handling produce better pets and better breeding stock.

Handling and testing — gentle handling and temperament testing, from day one.
Daily Life

Enrichment & Diet

Rats at Daisy Fields are raised in properly ventilated, enriched bin cages with toys, hideaways, and regular supervised out-of-cage time. Their staple diet is Kalmbach Lab blocks (18% and 23% blends), supplemented several times a week with fresh produce and nutritious treats for enrichment.

Community

Sharing Rare Genetics

I actively work on newer, rarer genetics and believe in collaborating with other ethical breeders — not gatekeeping. Sharing rarer genetics and encouraging more people to responsibly work on them helps the community and pushes progress in variety, health, and temperament.
