I once had a kitten with extra energy who loved to play with my hand like it was a kitten, scratching and biting and being so cute as he drew blood.

I bought an inexpensive oven mitt to protect my hand, and it soon became our new game. He loved to play with his "oven-mitt" brother and we had hours of fun with it.

As terrifying as it may sound, your kitten is sounding quite normal. Without a littermate to play with, he is relying on the humans to be his playmates.

(also, a long sleeved shirt is recommended when playing with the kitty an the mitt, as they do have a way of figuring out where the mitt ends and the flesh begins )

good luck and have fun.
