On Saltspring Island, I run Friends For Cats.
FFC was started in 2001, after I saw first-hand, while employed there, that the local SPCA ignored feral cats at best, and killed all the ferals that were brought to them, with the occasional exception of a few kittens. But most of the kittens were killed too.

Friends For Cats achievements:

At least 5 colonies have been spayed/neutered/released with a care-giver.
Many individual cats, or smaller groups have also been helped.

More quietly, Friends For Cats helps individual people with spay/neuter and other medical costs.
FFC routinely drops off food to people who can't always afford it.

This year, with the help of the AAS CatSnip program, Friends For Cats advertised free spay/neuter to whoever needed it. Approximatly 25 domestic cats have been helped this year.
