We have three cats that are fond of Madcap Mouse here in our home. This toy was the first one that our kitten Timmy went for when we first brought him home. We had picked up Timmy and his mother, sister, and brother from living wild at a local county park. Madcap Mouse was the first toy he went to, and it's still his favorite toy today. Timmy likes to grab the mouse in his front paws and kick at it with his back paws. He also carries the toy around the house, which is extremely cute to watch.
Here's a photo of Timmy the first day we had him, right after he found Madcap Mouse.
