I keep 20+ species of snakes. NO ball Pythons. I used to keep them going way back to when imports were the only availability.
For a first snake I never would recommend a BP. Now odds are you wont have an issue with a BP but for a first snake especially compared to a corn snake the odds are much higher. With proper care with corns you probably have a 1 % chance of an issue with a well started to adult. With BP's you probably have a 10 % chance of an issue with any age BP.
BP's can go off feed at any time. They can go from FT to live only for no reason. They will lay on a unregulated heat source or wrap around a heat lamp and stay till severely burned. BP's will lay in their water dishes till developing water blisters. BP's develop URI's mush easier than colubrids. Even BP's will eat another BP if kept together (never ok with any snake). Boy I probably have dozens of stories running through my head right now about problem BP's haha.
So many long time Herpetologists now categorize BP's as an intermediate level snake.
Wow !!
A fair bit of scaremongering there bud ....
You cant label them as poor feeders / quite likely to go on hunger strike and in the same sentence suggest that they're likely to eat a fellow Royal python if they're housed together !!
I've seen many reasons for not cohabiting Royal / Ball pythons but e risk of eating one another was never mentioned
