Does anyone else's cat go crazy for these? Often at night she's in the living room up in her tree and refuses to come down when I want to go to bed. All I have to do is get one of these out and she comes running. She likes to lick it a couple of times and then wants me to roll it all over her. I like to use it because it does get off any loose fur, I just think it's strange that she likes to be brushed with it, since it can't feel like much. When I need to use it myself, I have to lint roll my clothes while I'm in the closet so she can't get to it.
