i saw some substrate called T-Rex Bone Aid Calcisand. it's supposed to be sand that is made safe for digestion and adds calcium to their diet. it says for reptiles, turtles, snakes, and so on. it glows in the dark. i could not imagine this would be healthy to live in or digest. anyone ever heard of this? or used it? it would be a neat sand for hermit crabs....
also i put a cat collar in the old 55 gal. after cleaning it out and adding new bedding. it is cyprus muclh, mixed with shpagnum moss to add altered textured terrain for the snakes. i let it dry, and chopped a cat collar for fleas and insects into bits, and spread the 5 peices throughout the cage, to prevent any mite populations from trying to form. it has been in there for a good 2 weeks now. how long before i can put my snakes in there after removing the collar peices? 45 minutes to an hour doesnt seem like enough time? or is this fine? i dont want my snake to end up dead or with brain damage. i have read that putting them in the cage with the collar could harm them, but the collar works safe if you remove it before putting the snake in.
