Solutions – Cat Spay/Neuter Clinic

The Dumb Friends League — Solutions Cat Spay/Neuter Clinic offers services at reduced fees, subsidized by Dumb Friends League donors, to reduce pet homelessness and suffering. The spay/neuter clinic located at 191 Yuma St., Denver, 80223, serves owned, community, and feral cats. We do not offer services to for-profit breeders.

Surgery cost

Cat spay/neuter surgery is currently offered free to the community for all cats. Beginning January 1, 2021, there will be a $25 charge for spay/neuter services for owned cats. We will continue to offer free spay/neuter surgeries to trapped feral/community cats, thanks to our generous donors. Vaccines for rabies and distemper are included in the cost of surgery and will also be provided to feral/community cats at no charge. Microchips, FeLV/FIV testing and FeLV vaccines each cost an additional $25. We accept cash, check or credit cards for payment. No income qualification is required. Donations are greatly appreciated.
