Ethical rats,
raised with science
and heart.
Daisy Fields Rattery breeds companion rats with a focus on genetics, health, and temperament — pairing careful science with a lot of love, from downtown Denver.
Daisy Fields is a woman & LGBTQIA+ owned, ethical downtown Denver rattery — breeding since 2023.
Daisy Fields is a BLM/POC accomplice, anti-fascist, anti-ICE, and pro-Palestine establishment. As a rattery we believe kindness and equity for all people are essential — if you cannot be kind to all people, our animals are not a match for your home.
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.
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.
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.
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.
