I use aspen substrate, so I use a separate tub. All my snakes are in their own custom-built wood enclosures, so it's easier for me and they do just fine. In fact, they seem to know that when I put them into the tub ,it's go time. They never ball up or act scared. They usually look right at me as if to say, "ok, now where's the food". I put a f/t in, and bam! usually right out of my fingers. Except for my big female. She's srill on live, and I can't seem to break yer yet. But that will come in time. Just like the others.
