So I work at a resort, and we have two Sulcata tortoises. They're fairly large, as most 20(ish) year old tortoises are. We are looking to move them into a new, and better enclosure to where they have ample space and different natural enrichment to live in. However, on one side of the enclosure is a small (less than one foot) wall that has a deep pond on the other side. We've planned to put another fence or sort on top of it, but I was curious to know if there's any sort of rough estimate to the vertical climb of a tortoise is? Like how high is too high for them?
