I was one of the lucky ones who ended up in the forum before I got my Tort. I didn't venture into any other Redfoot groups or forums. I'm finding now that the information in these groups is contradictory to what I've learned in the forum. I've been using Cypress mulch as a substrate with no problem. This FB group for Redfoots says that Cypress mulch is toxic to torts and will cause all kinds of issues with tortoises. Is there any truth to this? Should I switch substrate?
