Hi, I have a 6mo old leopard tortoise. Actually two. One is very active and eats a ton. The other has eaten very lil, not active and eyes look to be shut.

I have an outdoor enclosure and an idoor one. They both range from 90-72 degrees Faherheight. I have a uvb bulb as well as a heat lamp. Put a cuttlefish in the cage as well as a lot of grasses and plants.

Im taking them to the vet Thursday but was wondering if anyone knew what was going on?
