I actually brought this subject up and every one wanted to be soo against me. But like I said on my thread, surviving is NOT thriving. Thriving is absolutely not eating, breeding, and pooping. And yes, just surviving animals will breed and eat.
I myself keep my snake in a tub but he has multiple hides, plants, stuff to climb around on and can stretch out fully and still have space to spare. People who keep their snakes like that are not thinking of enrichment and the well-being of the snakes, they are thinking of what is time, effort, and cost effective for them, and that definitely doesn't excuse what they are doing.
Just because snakes are of lesser intelligence than say, a cat or a dog, does not mean they should be subjected to life in a plastic tub with substrate, a water bowl and MAYBE a single hide.
