do the balls rattle? i'm trying to find non catnip non feather fuzzy rattle balls on long string like on the smaller cat condo of this brand.

Would this be good for a bedroom? I have a large cat tree in my living room by i want him tonight. Would this be a good choice?

how is this for bigger cats... My cat is about 12-13lbs and about 3 years old.

how big is it
