Ah, I get it. "Snabitat" is apparently the name that people give to snail enclosures (I didn't recognize the term, so I Googled it). I guess we crossed wires there. I'm glad I was mistaken.
It isn't so much that people are so into it -- it is mostly ignorance (willful and otherwise) of environmental/agricultural regulations and the smuggled history of their critters. The invert hobby is pretty bad in this regard.
