I am assigning no such thing. Those are all the needs of the animal. Now can you point out where i have assigned human needs?

Snakes need mental stimuli. Snakes need a suitable environment. (Meaning size as well)
In fact, if you are doing anything else other than trying to match the animals native environment as best you can, you are the one attempting to assign human needs. You need it in a small cage, you need it on a substrate easier for you to clean, you need it to eat f/t, etc etc.
