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.

We are no longer scheduling appointments for the Dumb Friends League Solutions – Spay/Neuter Clinic at 191 Yuma Street in Denver. As the increase in COVID-19 cases impacts our community, we must ensure that we can continue offering vital services to pets in need. While the decision to suspend spay/neuter services was difficult, it is necessary because it will allow our talented veterinary teams to focus on our core essential services; providing shelter and care to homeless pets and urgent care to pets in our community. We will regularly reevaluate the suspension of this program and look forward to resuming this public service as soon as feasible.
