Ok /an/,

There's a cat outside my door begging to come in. I've never seen him around here before though I've seen a lot of strays around here. He's missing a patch of skin around his neck.

I don't have any food for a cat around my apartment. Mostly just halloween candy and frozen stuff a cat wouldn't eat. I really don't know if I should feed him because I'm around it will start hanging around here. My land lords don't allow us to have pets and call animal control on animals that hang around here.

What should I do /an/?

Pic related, it's the cat.
