I think I saw that thing on an infomercial. It looks like it would drive them bananas!! My problem is the older female cat has been here for 12 years. I came along when I got married to her human 11 years ago. I had 2 older cats who eventually passed on so we rescued a little black cat. So he's a male, Boo Bear, and he torments Sammie. He wants to play and she is OVER it!! Before Hurricane Sandy we had Boo at the shore and Sammie inland. After we had to evacuate both cats had to come inland and they do not like being in the same house together. I'm hoping a huge jungle gym for them will give them each their own spaces. This one goes to the ceiling and has multiple levels and 2 houses on it so fingers crossed....they will be experiencing kitty nirvana by the end of the week. If it goes well I will post an off topic photo. 

Helps to figure out which toys they will each play with and wear them out each day playing, too.
Some of the automated toys can help with that. Have you seen the fling-ama-string? My friend's cats adore theirs. I'd get one, but I have very few doors downstairs...
