Hamster balls are for human entertainment, not hamsters. Do not put the hamster in the hamster ball.
No water or food

If your hamster determines that he is hungry or thirsty, there is nothing he can do to meet that need. It cannot leave without your permission and intervention.
There is no designated bathroom area

When your hamster urinates, he rolls with a strong, odorous liquid. Hamsters are not like dogs that have an affinity for spinning in odorous substances. Hamsters rather value neatness. And they even show certain areas of their cage where they have to urinate. So if you don’t like urine-covered hamsters, imagine what poor hamsters think!

It’s easy to forget that the hamster is inside

This is probably one of the most common problems and leads to very sick and dead hamsters. It’s easy to forget that you have a hamster.
When cleaning the cage, all you have to do is put the hamster in the bowl. But what about hamsters if you get a call while cleaning the cage or they call you elsewhere in your home? You can join another project that takes 20, 30, 60 … 90 … minutes. It’s been a while since I didn’t have water. And what if you put the hamster in the ball except when cleaning the cage? Again, if staring at the ball isn’t your main focus, it’s easy to focus your attention elsewhere. (This is even more likely if a child who is already alert is put in a hamster.) If you store the hamster ball on the floor, you’re probably used to it there. Therefore, the ball and hamster may disappear inside later. Or you’ll see a touch of the ball, but that’s it. I can’t see the hamster, so I don’t notice that the ball contains an important pet.

Ladder and hamster balls are a deadly combination. Cats, dogs and toddlers may think of the ball as a toy. Will you take the hamster out of the cage and throw it at the wall? However, this is basically what happens to a hamster if the ball is accidentally pushed, rolled, thrown or kicked. Your hamster is trapped.
If your hamster wants to get out, take a break, and walk on level ground for a while, you can’t.
Being in a dark closet

You may find it very fun to roll on a human-sized hamster ball. And I don’t, but he will enjoy it too. However, there are two important differences between a hamster running in the ball and a human playing in the ball. For one thing, you will be in the human hamster ball of your choice. Second, almost every human-sized ball I’ve seen is transparent enough to easily see where you’re heading, or at least translucent. That is, you are still using your first sense, you can see. You do not experience sensory deprivation.
But in balls made for hamsters, animals do not come in at their own choice. He doesn’t know where he is heading. What’s worse, the surface of the ball is muffled and blocks odors. Therefore, the hamster does not know where it is and there is no reference frame. In fact, the hamster feels like he’s in the ball as if he were trapped in a dark closet where the floor doesn’t stop.
Do not torture your beloved pet in a hamster ball.
