Review on Transparent 4.9-inch BeSimple Hamster Exercise Ball - Mini Running Wheel for Dwarf Hamster, Small Animals - Small Pet Rat Mice Running Activity Exercise Ball - Pink by Paul Romero

Hamster balls are very dangerous and distressing to rodents, regardless of the size of the animal or ball. Please do some research on why hamster balls are not recommended before buying toys for your little friends. The minimum mouse wheel requirement is 8 inches. Anything else will lead to back problems. This ball is not 8 inches in diameter! Hamster balls also make it difficult for them to hide or leave the ball whenever they want, making them very stressed. This is an unsafe form of fortification. Instead, create a safe environment away from predators so they can roam free without the ball.
