Does putting prey in PVC pipes count as enrichment? Been doing that since the 70's. Always clean what goes in an comes out of your cages.
I really like using rope. Now, that most of the cages are AP PVC, I run an eye bolt an attach ropes for the noodles to climb or hang on. Rope is cheap, use it an toss when it's time. Netting can work but the hole size has to be larger then the snake. Safety first an all that.
