A kitten ran up to me last night...

While it was pouring rain. Couldn't be more than a couple months old! I wrapped him up in a blanket and took him back to my apartment.
I'm not sure if I'm keeping him or not - I have two other cats and live in a one bedroom apartment. Stella likes him and wants to be friends, but Ollie is less than thrilled! He growls and hisses at him and his tail bristles. He lays down and watches him from afar. I don't like hurting my cat's feelings or make them feel like they're being threatened. any insight as to what I should do?

Here's a picture of the kitten

Oh, sweet kitten! Do you think he might have a home? If he's friendly enough to run up to strangers he's not feral, it would be a good idea to get a vet to check him over to see if he's chipped. Maybe put up a few posters near to where you found him as well.

If you do decide to keep him you'll have to carefully introduce him to your other two cats. You should keep them separate for now, just in case he has anything he might pass on to them, fleas or something worse.
