Hey there, snake newbie here! I've been researching a lot into ball pythons and I have a few questions about plastic bins as an enclosure. Firstly, if I use a heating pad that will go under the bin will I still need a climbing tree, I read that they're for the snake to get closer to heat but if the heats under do they still need this for exercise or enrichment? I also wanted to know if I will need to get different sized cages as the snake gets bigger, I know that bp's don't feel secure in big, open spaces so should I use a smaller cage for a baby snake?
