The Dumb Friends League offers affordable spay/neuter services to all owned, pet cats and feral/community cats. We are able to offer these services thanks to the generosity of our donors. We are not able to provide these services for-profit breeders, or rescue groups at this time. We recommend that tame, friendly cats without owners be taken to an animal shelter for adoption.
- Your cat must be 2 months old and weigh 2 lbs for spay/neuter surgery.
- Pets less than 6 months old can eat normally the morning prior to surgery. Pets 6 months or older should not eat after midnight the night before surgery. Water is okay for all pets prior to surgery.
- Pets 8 years and older require bloodwork prior to surgery. Please visit your regular Veterinarian to obtain bloodwork prior to scheduling. This service is also available through the Dumb Friends League Veterinary Hospital for an additional fee. You may contact the hospital at 303.722.5800 for more information.
The spay/neuter calendar is opened several weeks in advance. If you are trying to book an appointment and do not see anything available, it means that our calendar is full. Please keep checking back for availability, as cancelations happen and appointments may become available.
