You know, in a way that’s true. He does crouch and hunt, kind of. But when he plays with Jim, he’ll play like he’s going to attack (lurking around a corner, etc), but then he lets it go. I did fail miserably in the litter box area. He uses it faithully but doesn’t do a good job of covering the mess!
He’ll jump at a stick with string, (but lately, not as high - that’s probably the extra weight).
One of his favorite things to do, after he’s destroyed one of the stick/string things, is to use it as a battering ram. See this URL - The pix are about a year old, but you get the idea! <jumi-shirley-butler.com>—Shirley
