Aggression over fuzzy mice

Okay, this isn't really problem, (its actually quite adorable) but it is cat behavior, so I figured it fit better here. :)

We just got a couple of fuzzy mice (the ones made out of rabbit fur) and I gave one to the furbabies this morning. Mozart stole it immediately, and hid behind th refrigerator...GROWLING at it!

It was especially amusing, because noodles wasn't anywhere nearby...Mozart was just growling because he could!

What's even cuter is that when you pick up noodles while he has one in his mouth, he'll growl at you. When the cat is less than two months old, this isn't exactly terrifying. ;) He's not truly aggressive though, he's just growling! You can take it out of his mouth and he'll just mew.

I've never had two such wonderfulyl playful cats before. Certainly not as sweet and social as these two!
