My guinea pig loves to chew on these and make a big mess, but she usually cleans up the little pieces that fall all around her. It keeps her happy and healthy.

Pros: great taste

Cons: messy

i like my pigs cage to look VERY clean all the time and it does get pretty messy but they love them and it is mostly healthy so its wroth it!

Pros: it keeps their teeth from growing too fast

Cons: messy

I give these to my rats. they love the taste, but I think this brand sells treats/food high in fat and sugars

Pros: taste good

Cons: might not be as healthy

My guinea pig goes crazy when I put one of these in his cage. He loves them.

Pros: taste

Cons: none
