cat biting

[AmandaPants]

I have 2 cats, one is hairless and the other is a regular tomcat. The tomcat "Elvis" has been having difficulty with biting. He seems to bite my hairless when we are not home. I come home from work and he has bite marks, redness, and occasional bleeding from biting. Elvis does not have claws, so I know he is using his teeth to fight. I am wondering why he is doing this. We have recently moved into a larger home, and I thought this would help give them space. I am concerned I will have to get rid of Elvis as it looks as if my other cat is being abused.
We have tried increased play and changing of food. I am not sure what to do as I cant have a cat who is mean to my other cat. He is also neutered. I am unable to discipline as I do not see the incidents happen.
Please help!!!!!

i will include a site with some info that may also be of help, please do not give up on kitty without trying everything possible. can you separate the cats when your not at home?
also try FELIWAY a room spray that is all natural and helps to calm kitties...its also very useful for trips to the Vet or anything that causes them to be afraid. its available at most Vet clinics and and good pet shops....

They might be fighting, they might be playing.  If they are fighting, they should not hold back from doing it in front of you as well as when you are not home -- kitties into dominance fights do it whether Mommy is standing right there or not.  I'm not sure I would have a declawed cat and a cat with claws in the same household, since they will of necessity even play differently, much less fight differently, than each other, due to the disparity in weapons.
