This thing is pretty cool. The rodents decided it wasn't entertaining enough for them so its become mine. It smells great (a mixture of wool and NIP!) and has a leather tail which is so much fun to chew on. I approve this toy for use by cats who like wool. I like wool....its kind of the unmentioned Charmer in my life. I like the Woman's sweaters in the way that Tripper the Psycho Cat likes his stuffed girl friend. I give this toy 2 paws up. Oh, we got it from Siamese Rescue. For some reason they actually DO sell the best cat toys, beds, etc. plus the money goes to help cats in need. And if the Woolie Bullie gets out of shape you put it in a sock in the washy thing and it comes out brand new.
