You hamsteak trash xD Vriskat otp.
I've read this paper and the conclusion was inconclusive saying that it needed more reasearch and a few of their key points are bases off the thought of, "how would I feel if I where this snake" and anthropomorphizing.
As for the scientific proof needed to prove that it doesnmt affect the animal's life, look around you. The spider is and always has been thriving the same way all other ball pythons do in captivity. They do all the things any other ball python does. Ball pythons are relatively simple creatures who just want to feel safe enough to eat, shed, etc. that's all they want. They don't need anything else. They don't need a branch to climb to "stimulation." They just want to hide and be left alone.
