An exercise ball can injure their back, which means exercise wheels are also out of the question. You are probably wondering why people sell exercise balls if the are not good for your cavy. Some manufactures say you can use them to keep your guinea pig in while you are cleaning their cage. If you have a small guinea pig and a large ball it could work but you should consider getting a guinea pig travel cage or guinea pig carrier for safety’s sake to place your piggie in while they are waiting for you to clean their cage. Eventually your guinea pig will grow and I'm sure you don't want him or her to get hurt.

There are better ways to exercise your guinea pig. Alternatives to exercises balls are small balls with bells in them (think cat toys) your guinea pig can push around his or her cage and have a good time.
