Caring for the unowned cats of Sonoma County
1 cat spayed today prevents 11,801 cats from a life of potential suffering
Over 40,000 cats altered since we began

What we do

Spay and Neuter

With more than 45,000 cats altered to date, we are reducing the population of unowned, free-roaming cats eliminating health issues, euthanasia instances, animal abuse and neglect before they can ever occur. Learn more

Colony Management

FFSC maintains a large number of colonies throughout the county and whenever necessary will assist the public with any problems related to colony management. Learn more

Adoption & Wine Country Barn Cats

After work in foster care homes, many wild cats and kitten become adoptable and are searching for a new home. View our adoptable cats.  However, sometimes they aren’t able to be fully socialized and are relocated to rural properties where they can work, be cared for, and lead happy healthy lives.
