If you put it on the top platforms he will jump up to it, grab the tail in his teeth and throw it off. He gets some pretty good distance too. Then he looks at you to get it and put it somewhere else on the tree. The first picture is him snagging it off of the top of the round part.
He sure looks as though he's having lots of fun up there! Is he an only cat?
Only cat, but we do have a older dog. They are getting better about getting along, but as a kitten Max (the dog) was Lynx's favorite toy. He still stalks him sometimes, but doesn't pounce as often. Poor old Max just looks at us with those big brown eyes that say "Why did you do this to me?"
