Review (4/5): My cat is very happy.
Basically, I agree with what other people have written, both good and bad. I love these for my thick, heavy hair because they actually stay put, but I don't use them as a first choice because they're hard to stretch out and will take a lot of hair with them if I'm not careful while taking them out.
However, My cat adores them and fishes them out of my nightstand drawer. He doesn't seem to be at risk of choking, and he brings them to me for fetch. They heft gives them a satisfying distance that is way better than light felt items, and the will bounce at odd angles when they hit the wall. This price is pretty good for a favorite toy!
