My boy, Mo, has always been a bit on the aggressive side to me, too. I’m not learned in cat behavior, since he was the first cat I’ve ever owned as an adult and I wasn’t prepared for the biting, etc. He would bite and pounce all the time, even after a play session (although those did often help). I would come to work with bandages all over because he just would not stop! I became really good at cleaning a wound, though. 😉
As he’s gotten older (he’s 2 now), this aggressiveness has ebbed, and play sessions wear him out much sooner than they used to. Kittens just seem to have boundless energy. Even so, he still liked to viciously attack my legs as I walked to the kitchen to feed him every morning. I solved this by getting a laser pointer to distract him as I walked downstairs. He’s just excited about being fed and playing/hunting is a natural predecessor to eating. For me, it helped to understand the behavior so that I could address it for what it was – a playful hungry cat.
I think over time he will not be nearly so aggressive. I felt it was odd too, when he was doing that to me as a kitten, but I think maybe some boys are just built a little tougher. I have no idea for how long Mo was separated from his momma as he was found already abandoned, so he could very well be much like yours!
I will also close on this: we recently got a new kitten, a girl, who we adore. She’s precious, but has recently started the biting thing. I’m not ready to say yet if it’s as bad as Mo’s, but I will say that getting a new kitten feels a lot like starting your cat training all over again. You get to used to that ONE or those TWO cats behavior that any new addition or new kitty seems totally different. I guess this is because it’s true – they are all different. And no cat is typical!
I think you guys will be just fine. Good luck any way! Keep that alcohol-ointment-bandaide combo handy!
