I always forget how so many people don't have grass lawns unlike here in NC. We have Bermuda/fescue (no idea if that was spelled right) which my baby redfoot will nibble on when she gets outside time, they are definitely not grazers. I've heard that people who do use grass will just plant a tray full of grass seed and stick it in the tank when it grows. Good luck. I have also worked with various lizards/amphibians and tortoises definitely seem to require a different mindset.
