I always find it funny how someone will tell you how you should keep your snakes because their way is best (not talking about animals needing troubleshooting because of specific issues)
There are many ways to skin a cat and people needs to be more open minded, yet to some keeping a snake in a tub is borderline animal cruelty and the animal is barely surviving
I have been keeping Ball Pythons in tubs, just a tub and a bowl of water for over a decade they don't just survive they thrive and they do as well as animals I have previously kept in cages or tanks.
Why?
Their needs are met and they live in a stress free environment, as a result I never had an animal with a RI, immune system issue, scale rot etc.
They eat, they breed, they spend 80% of their time hiding as they should do you think they would do more if they had an enriched environment? If so what would they do?
The issue with the first study is that it goes beyond the scope of snakes it talks about large lizard as well as tortoises which in this case is a whole other story., but this thresd is about Ball Pythons in tubs since this is where it was posted.
Bottom line people should not worry so much how others keep their animals so long the animals are healthy and thriving, people should keep their animals the way they are without being judge especially by people that have likely little to no experience keeping animals in setups they despise so much.
