Thanks. Along with this toy issue is the question of when to break up a fight.

Pesto usually "starts it" with Smudge,and Smudge (being 4 yrs older) doesn't want to bother, gets annoyed, and growls. Then they play/fight.

Then, they start bearing their teeth (really scary) and growling a LOT. It scares me so I separate them out of fear they may do harm. Should I? Or should I let them fight? How do I know when to intervene?

Ugh. Fighting over toys and just plain fighting. I know it will get better, but I'm trying to figure out how to best handle these situations in the meantime so I can have a happy family

Thanks.
