We have visitors in the back yard, including all sorts of birds, chipmunks, squirrels, stray cats, and raccoons.

My cat cannot cope with the visiting cats. She is mildly inflamed by raccoons, but the cats, oh no.

If she sees one, she goes barreling at the sliding glass door and hits it with the full weight of her 16-pound body while punching the glass with her paws. She is ready to KILL.

It's pretty loud, and we make jokes about her shattering the glass. She can't shatter the glass. I think.

Actually, I'd better google that.
