Two Kitties cont....

Question
I just thought of something else. I just previously asked a question. Also my one kitty that is having issues....growls to herself when playing or growling at the mouse or ball. Is this normal?

Answer
All within normal. Kitty is really just practicing her hunting skills which is normal for kittes even if they never need to hunt in their future. Its instinct to play as a hunting practice. If you see signs of being very agressive as in consistently biting or otherwise attacking, check back with me, but so far nothing seems all that odd.
