Noah used to do this too, but he's stopped.

Here are a few things that worked for us:

*When he bit us, we would get up and walk away. He didn't get rewarded with attention while he felt biting was "ok".

*Distact him from our hand onto a toy. Catnip toys worked best, it would grab his attention quicker.

*The squirt bottle worked for us.

*Getting a KITTEN. This really worked...as soon as we got Noel...he had someone to work his aggression out with. He never got mean, they just played like cats are suposed to play.

Something that is working to calm Oliver is Feliway...you may try spraying that in the air during an "attack". It really calms Oliver down.

Don't worry that you are alone. When Noah used to bite, I was his target. I actually cried a few times, it hurt so bad, emotionally and physically. Now, he's almost 100% better and he is my heart...I love that cat to pieces.

Good luck!
