Before you get ANY pet, you need to research care. This includes basic pets such as cats, dogs, fish even. Some people say guinea pigs are easy, mine sure wasn't. Some people say cats are easy, I had one pass because of a blockage in his urethra and couldn't pee. My dog gets demodectic mage once a year (she has an immune system disorder) and yet dogs are considered "easy beginner" pets, hence people get them for their children to care for.

Same with balls, once you research how to care for them, the really are easy to care for. Check your temps, fed every so often, clean the cage, keep the humidity a certain level. Not much different. If you really are responsible you will do the research.
