I can't be 100% sure of the mulch, the pic is a little small, but it looks like cypress mulch. Where did you get it? Why wasn't it labelled as cypress? Anyway, bowls aren't any good because the crix will just get out and run everywhere. How big is the tegu? Smaller animals are usually more at risk for impaction. I recommend not feeding crix on the mulch. They can hide in the mulch and there is always the risk (however slight) of impaction. Tegus are really good at avoiding eating the substrate. They will rub their snouts and wipe their faces with their claws to remove debris. Still, I think it is better to go buy one of those plastic large kitty litter pans. Watch the crix though, the really dedicated ones can climb out. For the most part, the crix can't climb out and there is no risks, plus easy cleanup once little buddy is full. Add tegu crix and watch him go nuts!
