If you are looking at ways for your hamster, gerbil, mouse, or small rat to get some exercise, check out the ever popular hamster balls. A hamster ball is a hollow ball made of clear plastic with air holes and a removable doorway that you can use to put your hamster in the ball, or take your hamster out.

Hamster balls provide a great source of exercise and mental stimulation, since they allow your small pet to get out of his cage and explore a much wider world – your home. Since hamster balls are made of a durable plastic, they end up making some noise when your little pet rolls over hard floors. That, in addition to the bright colors and at least 5″ diameter, helps make your small pet easier to find while he does his exploration. It’s a much better option than trying to keep track of your little critter, since he cannot get under furniture or inside walls. Hamster balls are also great, secure places to temporarily hold your small pet while you clean the cage.

When using a hamster ball, you want to make sure you either are on a low level of your home or block the stairs so that your small pet can not accidentally take a trip down your stairway. Stairs and other high places are hazards to your hamster when he is in the ball, since your hamster could fall and suffer a serious injury or even die. While hamster balls do protect your little pet when he is roaming the house, they are not bubbles!

If you are wondering what size of hamster ball to get for your small pet, here is a handy chart you can use. Remember, some small pets may be larger or smaller than the breed’s standard, so you need to take your individual pet’s size in account when buying a hamster ball.

Ball Diameter Size Small Pets
5″ Mini or Dwarf Dwarf Hamsters and Mice
7″ Standard or Medium Hamsters, Gerbils, other small animals
10″ Jumbo Guinea Pigs, Small Exotic Rats, Hedgehogs, and Chinchillas
12 1/2″ Mega or Giant Large Exotic Rats, Guinea Pigs, Chinchillas, Ferrets, Hedgehogs, and other small animals


If you are looking for a way to exercise your pet rabbit, chinchilla, or guinea pig, it is advised that you find something other than a hamster ball.  Rabbits have different body structures than small rodents, and being placed inside a hamster ball could cause them serious harm.
