She sometimes does bring it back and drop it again, but I have gotten where I can throw it almost fully asleep. She seems to only want to fetch the mousie 3 or 4 times each session before she gets bored with fetching and just plays with it by herself.
See, that doesn't work for me. That's where the fetching thing is a problem, I suppose. As he just runs back with it so I'll toss it again! And those claws are sharp, so when he's pouncing around the bed playing with his toy, I get claws poking through the comforter into my legs!
