I...actually don't think so. At least not healthily. I've got a rescue snake who was found in someone's yard I think a little over a year ago; I acquired her shortly (about two weeks) thereafter. She was an adult when I recieved her. She was missing the tip of her tail, had a number of scratches, cuts, patches of missing scales, a big cut down the center of her head (which took MONTHS to heal), stuck sheds, massive areas with missing pigments, old scars, and while she was the same length as my then 2100g adult female, she was visibly underweight with her backbone standing out and a very "triangle" shape to her. I estimate she weighed 1400g at the most.

Even now a year later she still has scars, and the patches of missing pigmentation still haven't gone away. She only weighs 1960g, and I'd like her to be closer to 2200g. So, no, I don't think that balls are suited to living in Florida. Not that they cannot, but I seriously don't think that they would establish such a large and successful breeding population. At least not as successful as burmese pythons, in any case.
