Fostering siblings cats for a little bit need advice.
Basically, my sister's house burnt down and her cats need a place to stay. I currently have a male cat, and I believe both her cats are males (At least one is) I have a room ready to quarantine and my dad is picking us up an extra litter box. My cat is going to the vet on Wednesday. I think one of her cats is going to the vet first because he is older and inhaled a lot of smoke and I'll be getting him Monday.
Any advice for this situation? When I got my cat from a shelter three years ago they said that he was good with cats. That was three years ago though and he hasn't been around other cats since. (And we don't know his history as we got him at three)
