Since last Summer my neighbor’s cat (I call him “Spunky”) has been hanging out at our house (don’t know which neighbor owns Spunky). Spunky is a young cat about 2 years old. He has a collar but no ID tag.

Spunky likes our cat. They seem to be good buddies.

I have an ID chip reader cat door that’s supposed to limit only access to our house to our cat. But Spunky can still get into the house by following our cat through the cat door. Spunky just waits for our cat to enter or exit and he slips into the house where he makes himself at home (plays with cat toys, sleeps, eats, drinks and uses the cat boxes).

For the last week Spunky has not left our house. So I put up signs in the neighborhood and on a local animal lost and found website.
Waiting for someone to claim Spunky.

Spunky has no ID chip (my cat door doesn’t find one).
Spunky is not neutered and that tells me that he likely hasn’t been to a veterinarian for mandatory vaccinations. That’s a big problem. It’s gross negligence.

If no one claims Spunky then I’ll adopt him and make sure he gets regular veterinarian care. He’s very affectionate and a good companion to my cat.

What more can I do besides start knocking on doors?
What do you think?
