I think that she thinks that she is a cat. This is hilarious........ I picked up a squeaking mouse on a wand for the cats as I was taking it off the cardboard that it came on Julie jumped out and started chasing it everywhere and playing with it. She is attracted to the squeaking and will chase it and grab at it. It is too funny. Now I can't give it to the cats though. I volunteer at a cat rescue/retirement home. It has cat nip in it. Wonder if she likes that. She had a cat mouse when she was a baby and played with that a lot.
