The length of the exercising program depends on your pet’s immune system, endurance, and personality. Hamsters can easily get lazy, especially if you provide them with more food than they require on a regular basis. Thus, we cannot precisely tell the time your pet should stay in such a ball.
It also depends on the rodent’s personality and interest, as some animals may not be attracted to this type of entertainment. However, don’t be too quick to judge your hamster’s personality and try to put it inside the ball a few times before deciding whether or not you should keep it. Some rodents may take up to one week before they get used to or develop an attraction toward a certain toy.
