Spay and Neuter
With close to 50,000 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

Cat Adoptions

Each year we place hundreds of cats and kittens in permanent homes looking for a new lease on life.  


Our Adoption program finds homes for tame adults we find living in feral cat colonies and for formerly feral kittens who have been tamed and socialized by our volunteer foster parents. 


Since we place cats directly from foster home to forever homes, cats and kittens spend more time socializing with people and less time in a shelter environment on their own.  

Forgotten Felines of Sonoma County is a nonprofit Spay/Neuter Clinic focused on improving the lives of unowned cats in our county. We are the longest-running Trap-Neuter-Return (TNR) organization in the country, and we have been serving our community since 1990.

Our mission is to spay and neuter every unowned cat in Sonoma County. For those unowned cats that visit our spay and neuter clinics, we also provide medical care for sick and injured cats and find loving homes for adoptable cats. We rely on the generosity of our donors and the dedication of our volunteers to continue our important work.


We can’t do what we do without a fantastic group of volunteers. If you are interested in volunteering, click here and we will contact you to share how you can make a difference.

If you

It's incredibly kind and generous of you to give food to cats wandering in your neighborhood. But we have so many "unowned" community cats in our county.


The more they reproduce, the more challenging it is to care for them.


If you feed stray cats, please call us to get them spayed or neutered: (707) 576-7999.
