I'm sure some of you are aware of this, but I thought I'd bring it to your attention since I haven't seen it mentioned on here.
If you have any species of tortoise, you probably have never seen it drink water. Most tortoises get their water from plants, primarily cactus in the wild. At the zoo I work at we have a Cali. Desert Tortoise and an African Spurred Tortoise. We used to have two other African Spurs and both of them had bladder stone problems due to dehydration (all of our animals are rescues). After talking to people at UIC we found out that feeding them high water-content vegetables was very important for any tortoises health.
We use cucumber, and feed a whole cucumber every day and our current tortoise had bladder stones that had to be surgically removed a few years back and now is completely free of them since we started feeding the cucumber.
