Is this behaviour normal?

Hi all

My coastal has become very aggressive whenever I place him on the back of the kitchen chair. Normally, I can place him anywhere and he is quite happy for me to pick him back up, but whenever I put him on the back of the chair he will form the "S" shape and hiss at me. Last night he striked me about 3 times.
The chair is made of treated pine. He is in love with this chair or what??

Probably is thinking he can hunt off the chair, how long since you fed him?

He had 2 x fuzzies on Sunday. He is just on a year old.
He has only just started this odd behaviour about a week ago.

I would say he likes the chair. If you tried to rip me out of my fav chair when I was relaxing I would probably strike out at you too, lol.

So, do I have anything to be worried about?
