My 45+ year old tortoise has spent several days in her water pan. She's had her head up and been looking at me when I look at her. This is in her outside home where she spends the summer. Today she looked like she had drowned. Head down in the water and very slow to respond when I touched her shell. She's usually quick to move her legs when I touch her even when she's asleep. So once I assured myself she was still alive I took her into her inside pen which has no water. Her legs where they enter the shell are very swollen and puffy. She laid all stretched out and when I picked her up was sort of floppy. All this was 2.5 hours ago. She's looking better now. Holding her head up and looking back at me when I look in the pen at her. Eyes and nose are clear and dry - no discharge. Her indoor pen is at 80 degrees. It was probably 85 degrees outside but it has been a lot hotter and she hasn't seemed to mind unless it was over 90 for several days in a row (not so far this year) and then I brought her inside to cool off. Any ideas about what is going on here? Has this happened to anyone else's tortoise?
