I don't intend to keep them all (I promise) but I'm having A LOT of trouble finding an organization that will help me. I've tried our local animal control (left numerous messages, no return calls), local shelter (will only take animals if dropped off by the animal shelter, also they euthanize ferals), and a volunteer-run animal alliance (foster homes are full, subsequent emails went unreturned). Tonight I sent an email to a rescue group my vet recommended. Hopefully they can help. My last resort is a fantastic organization in MA that would take them - but it's in MA. So. Hopefully I won't have to drive them all the way up there.
They are feral, in the technical sense, I suppose. But kittens are very easy to socialize - I can't just give up on them. And besides, if they did make it through the winter outside, next spring there would just be more kittens. There is no trap-neuter-release program in this area.
So yes, I did what you are not supposed to do - I fed some strays, and then let them in my basement, and now they are my responsibility. I'm ok with that.
