Your kitty is so cute!

How old is your kitty? It could be that she is just not done growing up yet.

I don't know about the breed being friendly or not, but I do know that our spayed female (now three years old) can be very sweet one minute, a terror the next minute, and a grumpy old woman two minutes later.

She is the littlest of the bunch, but makes up for it with her attitude.
