This is about the cheapest chew toy you could get a small animal. It's cute, less than $2 and if you own rats it wont last more than a day before the rope you attempt to hang it up with is chewed through. My rats in particular didn't have too much interest in it after the first week or so but I've heard many other good things from other people. Thus, I'm chalking the disinterest up to them being girls and being too busy for lava stars or other distracting ornaments.
