ChewmonkeyBC,

I have a question...are the cats neutered? If not, that's probably the reason why. Whole (not neutered) males will fight for territory. Before you have to go picking which cat to rehome (I think it's unfair of your Mom to make either one of you choose) you might want to have them neutered. This will DEFINITELY help.

I could NEVER choose from any of my furbabies to rehome. I love them like they are my children. When you have a multi-cat household like yours (and mine), there will be confrontations from time to time. It's just nature. As long as there is no blood shed and no one gets hurt, the best thing to do is let them sort it out.

I'm sorry your Mom has put you in this situation. I hope she will reconsider. Good luck and let us know what happens.
