Our ferrets don't really play with this together, but when in the cage one of our little girls really loves to try to chew on this and listen to the bell ring!

Pros: ferret enjoys playing with it

Cons: Others not so impressed.

I like that this came in a two pack. Our ferret loves bells so this ball is extra good. We got some other ones for cats that broke. These are stronger.

Pros: bells are great

Cons: none

My guinea pig loves picking the ball up with her teeth and dropping it. Also pushes it around and likes the noise the bell makes. It's a source of entertainment not only for her but for me as well while watching her play with this thing.

Pros: the holes, bell

Cons: none really

all the ferrets i have known love these things. they think it is a neccesity for thier lives.

Pros: ferrets love them

Cons: can get annoying
