Is it hard to take care of a ball python?

it all depends, just like any animal it need proper attention from cage cleaning to handling and feeding. I would recommend trying to learn a little about owning them as a pet so you know its feeding times and how to handle/care for it. Remember they do tend to get very large so you have to be prepared for that as well and know it eventually will happen and you need to be able to accommodate for that. Just a tip never hold a snake during its shedding period they tend to have blurry eyesight from this and may end up biting you by mistake also i wouldn't recommend handling it after feeding.
