since I work in a cardboard fox factory I have ease of access to make things for my snakes. I've had a bit of sucsess and a bit of failures. The most notable failure was something I've made and used double sided tape to stick it to the aquarium wall... the tape didn't stick, but the snake did, 2 hours of careful peeling with a wet qtip and what made it worse was I hadn't discovered it until 24 hours later, the snake was nearly stretched flat. But the baby corn snake survived and is now in the care of another person and over 4 feet long. Since then, no tape in aquariums at all.

I'm making a cardboard tower, it will be big enough for baby garters prolly up to 6 months old. it has 3/4 square of room in the crawling space, goes in a square, middle is cut out and walled. There are 5 floors, enough room to crawl in the middle and climb on the outside. Pictures later.

I'm not sure it will work, it just might be a bit too small. But it only took me a few hours to build and if it works, I'll get about 6 months of use, then put it away for the next babies

Has anyone else besides me tried things with cardboard?

I've done shelves, hides and climbs, mazes, even made enclosures, cardboard tubes around the inside of aquariums
