My 2 yr old red-foot tortoise flipped over in the sun for around 30 min. Then when I back I flipped him back over and he started foaming at the mouth. I thought he was dehydrated so I soaked him everyday in the morning before I put him outside and after I take him back in. It has been a day or 2 now and he hasn't really been eating, he's been moving a bit but barely. I don't know what to do other make sure he's hydrated. please help
