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).

Meet the newest barn cats in Monroe!
You can’t see them in this photo—they’re tucked away in their crates, staying hidden like true ferals—but trust us, they’re in there, getting used to their new home.![]()
These two couldn’t safely return to their original outdoor territory, so they’ve joined our barn cat program, where feral cats are placed on properties that need natural rodent control.![]()
They’ll spend several weeks in these secure enclosures, with their crates acting as a safe zone, helping them acclimate and recognize the farm as their new territory. Once released, they’ll stay close, ready to keep the rodent population in check.![]()
This particular farm had barn cats who lived to be 16—these two are the next generation of working cats, living independent lives in exchange for food, water, shelter, and safety.![]()
Barn cats are typically feral and prefer no human contact. They thrive in environments where they can live freely while having their basic needs met.![]()

Tales from the traps for #caturday - this big boy was just trapped and he is definitely a HUNK! He still need to do a medical evaluation for him, get him snipped, and figure out a name for him - Louie? Alfonso? His trapper said his face feels like it is covered in scabs, but he is in good hands now. If you want to help us rescue more cats like this big boy we have multiple ways to donate right here - alleycatproject.org/donate/
PSA: Be sure your cat cannot get inside your walls, even if you think it's not possible or not a danger! We recently received a voicemail from a concerned cat parent - their cat had opened a panel on a wall in their apartment, and then climbed 8 feet vertically up into their ceiling! ![]()
We went to help out and saw the cat was way up high in an inaccessible area, so we were able to assist by moving a really long pole around to get the cat some food and water. Thankfully the building's maintenance crew were able to cut some holes in the walls, and she finally appeared! From there it was a waiting game, and she eventually came out all on her own. She was taken to the vet and treated for dehydration and a fever but is otherwise A-OK, whew!
