The Dumb Friends League offers affordable spay/neuter services to all owned pet cats and dogs. We are able to offer these services thanks to the generosity of our donors. This program is designed to help individuals in our community provide preventative veterinary care for their loving pets, and is not available to for-profit breeders or rescue groups.


Pre-surgery requirements

  • Your cat/dog must be two months old and weigh 2 lbs. for spay/neuter surgery.
  • Pets less than six months old can eat normally the morning before surgery. Pets six months or older should not eat after midnight the night before surgery. Water is okay for all pets before surgery.
  • Pets eight years and older require bloodwork before surgery. Please visit your regular veterinarian to obtain bloodwork before scheduling. This service is also available through the Dumb Friends League Veterinary Hospital for an additional fee. You can contact the hospital at 303.722.5800 for more information.

Day of surgery

  • Drop-off time for surgery is staggered between 7-8 a.m. Follow signs for Spay/Neuter Clinic entrance on the west side of the Vida Building.
  • You will be given a discharge time when you drop off in the morning. Pick-up will be later that same afternoon, but it varies depending on our surgery schedule, so a more specific time will be given to you the morning of surgery.
  • 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 for availability, as cancellations happen and appointments may become available.
  • Payment is due at the time of service; cash, check, all major credit cards, and Care Credit are accepted.
