I'm so sorry you are having problems with Ally and Connor, how long ago did you introduce him? It takes a while for cats to get used to each other, especially starting with a single female. They are the ones with the most attitude, however introducing a male is the easiest as opposed to introducing a female, so you have that on your side. Ally is used to being the queen of the castle and has what we call "sibling rivalry". She was used to getting all the attention and not having to share. This new situation has caused her obvious stress and I agree that Connor's deafness is why the introduction is taking longer to calm down. Their fights sound pretty serious and there is no doubt in my mind that Ally biting you was because of Connor, that anger was directed at him, not you. I have heard of Prozac for cats, and perhaps Ally needs that to help her through the introduction. My advice would be to buy the feliway and make sure you give Ally the attention she desires so she doesn't get AS jealous. Also, perhaps she would like her own litter box and food dish? She sounds like a princess and as long as she continues to be treated like one I think she'll be happy and will eventually have to come to terms with Connor. Keep them separated for now and supervise a daily visit, try to see what actions upset her and cause her behavior, then try to adjust according to that. Also, if your husband loves you, he needs to be understanding of your cat situation, threatening you will not help anyone's situation! Don't back down, you have a say in your pets life too! Regroup and try again, there IS a way, you just have to find what works best for your babies. Good luck!
