Alley Cat Project’s primary mission is to reduce the population of stray cats in Seattle through trap, neuter, and return of feral cats. We spay and neuter feral adult cats, and we foster, socialize and adopt out kittens as well as adult cats who have socialization potential. ACP is 100% volunteer run and foster based, and does not have a physical shelter.
What We Do
Here are some things we do to help Seattle’s feral, stray and abandoned cats:
- Trap, Neuter (or spay), and Return (TNR) feral cats to their colonies. TNR is a humane solution to the problem of unowned free roaming cats.
- Foster friendly cats who were lost or abandoned so that they can be redeemed by an owner or adopted to a new family.
- Socialize semi-friendly kittens and cats so they can be adopted as pets.
- Provide basic medical care, nutritious food, and safe and sanitary conditions to all cats after alteration.
- Alter cats through the services of Feral Cat Spay/Neuter Project (FCSNP).
