Solutions – Cat Spay/Neuter Clinic

As part of our ongoing efforts to reduce the number of cats on our streets and in shelters. The Dumb Friends League Solutions – Cat Spay/Neuter Clinic offers fully subsidized (free) spay/neuter surgeries and FVRCP and (age appropriate) rabies vaccinations for Colorado cats, including owned cats, feral cats, trap-neuter-return (TNR) cats and community cats (tame or feral free-roaming cats). Anyone can bring a cat to the clinic for spay/neuter surgery, regardless of income. We do not accept cats from profit breeders.

The facility and spay/neuter program are being funded for a three-year period by generous grants donated by the Animal Assistance Foundation, PetSmart Charities® and the American Society for the Prevention of Cruelty to Animals (ASPCA), as well as by the Dumb Friends League.

The Dumb Friends League Solutions – Cat Spay/Neuter Clinic is located at 191 Yuma St. in Denver, conveniently located in central Denver near I-25 and 6th Avenue. The clinic is operated by the Dumb Friends League and staffed by members of the Dumb Friends League veterinary team.

We do not provide services to animals who are not undergoing spay/neuter services.

Please note: Kittens need to be at least 8 weeks of age and weigh 2 pounds for surgery. We do not take cats 8 years and older without recent blood work, performed no more than 30 days prior to appointment date. Cats taking medication for any health condition should delay surgery until all medication is finished and treatment is complete. For patrons with cats being treated for chronic medical conditions, please call Dumb Friends League to discuss the cat’s specific condition and determine if surgery can be performed. We do not accept cats from for profit breeders. We will spay female cats that are in heat.

Do not feed adult cats after midnight the evening before surgery. If they are kittens under 6 months of age, feed them as normal. Water is ok for all ages.
