So far Cozmo is the only one to play in it. The other cats just don't play with toys much anymore. Maybe because they are getting older now and lost the kitten in them.
For Christmas Yvonne got the cats a long tunnel thing to play in, Cozmo was little then and played in it all the time and Panther would some times, but after a short time they don't go near the thing it just lays here taking up space.
I am thinking of giving it to the girl I got Cozmo from since she has kittens come and go all the time because of the adoption service she runs so maybe it will get played in there instead of collecting dust like it is here.
