My husband and I are trying to transition a young male cat who's been around the neighborhood for a few years. We left food out for him when we had two elderly cats indoors, but now that we've had to say good-bye to them, we're in a position to help the porch kitty. At least a month ago he started approaching us, talking a lot and asking to be petted. Started sleeping sometimes on the porch chairs and coming inside for a brief exploration. We started feeding him indoors two weeks ago, got some treats, catnip, and a toy, and premium fresh food to tempt him--plus calming spray, pheromone spray and calming treats (which he doesn't seem to like). He still only stays in for 10-15 minutes, but this morning he spent 15 min in the basement by himself. He's also felt comfortable enough to jump on a table to look out the window. He's been neutered/ear-tipped, and we think he's part of a nearby feral colony, but he exhibits behavior of once being a housecat--waits at the door, goes up and down stairs, follows me around. We can't take him to a vet unless we are sure he'll be around when we have an appointment. but are concerned that's he'll just go nuts if we keep him in. To complicate the situation, we just listed our house for sale and might be moving within 60 days, and we don't want to abandon him now that he's made the brave effort to be friends.
