Thanks for the reply! Is there anything we should do in the meantime to let him know that "Hey you're growling and hissing at the people that have taken care of you most of your life but that's okay because we still love you as much as we did when we brought you inside - and you're still our baby"?
We have an 8 month old male cat (named Milo) who we rescued from outside when he was a little baby. If we hadn't rescued him and taken care of him, he would have starved to death outside. He used to weigh .75 pounds but now he's a healthy 10 pound cat! He has his quirks and his own personality...
