I took in a stray kitten that someone dumped at my work back in the fall. I wasn't sure if i would keep her or not, but i felt obligated to clean her up and feed her while i figured out what to do with her. As soon as she started interacting with my other kitten, they became best friends and i couldn't in good conscience seperate them.

Another friend of mine slowly took in a stray cat over the fourse of a summer. Leave out food for it of it hangs out around your house until it starts to nuzzle up against you. Then you can pet it, maybe pick it up, and then take it to a doctor to get it checked out.

It sounds to me though, that the other guy just doesn't like animals.
