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.

Make an appointment

The spay/neuter calendar is opened up one month in advance, on the 1st of every month (unless this falls on a weekend or holiday). If you are trying to book an appointment and do not see anything available, it means that our calendar is full. Please check back on the first of the month to book your cat’s appointment.
