I had a one year old ball that escaped 6 monthes ago and I just found him a few days ago. He looks a little skinny and is moving quite slow. I thought he's jump right on that mouse but he doesn't want anything to do with it. I know he's got to be hungry, what can I do to get him to eat?

He's always eaten live mice and I've never had luck getting him to eat prekilled. Thanks for your help!
