He Wore Himself Out
The cats' new climbing tree has stairs. But, Mouse doesn't like taking the easy way and insists on climbing up the side of it. Climbing, however, isn't as easy as it was when he was just a kitten and pulling up that extra weight last night seemed to take a lot out of him. Shortly after making it to the top of the cat tree, he ended up flopping down for a nap and was out for about an hour.
