When I kept rattlesnakes, I made my own shift/hides out of lengths of black PVC drain pipe (various diameters, 8"- 4") for different size snakes. Very easy to work with,
& you can buy the lengths you want. I got the ventilated drain covers to match each diameter, & bolted one on one end, & put a handle on one for the other end (so my
fingers couldn't be reached by long fangs thru the vent holes...it's N/A for you anyway). The point is, snakes saw the dark cave as a safe escape & went in happily with
little stress; I still have them & even caught a wayward possum with one, he got in my garage & wouldn't leave, but he went right into the tube when I put it in front of
him. Wondering if a small black tube would work for Toref this way? Pretty cheap to try, anyway & what runs (or slides) in, easily slides back out at your convenience.
