I'm having an extremely worrying morning, really hoping someone can help me out with some advice! We have a sulcata tortoise, Morla. We don't know her age (she just showed up in our back yard one day last June, and we were never able to find her family). I weighed her this morning, and she weighs 17lbs, and is about 14" long. I think she may have lost a little weight since I last weighed her, which doesn't completely shock me, as she hasn't been very interested in coming out of her 'cave' all winter long. However, the weather is starting to get nice. Anyway, as it turns out, Saturday afternoon, while I was at work, my sister took her out and put her in her run to graze. Unfortunately, she forgot about her and didn't remember until about 9:30 last night. She brought her in and put her under a basking light with fresh water and timothy pellets, but Morla just took off like a rocket for her den. When I went up to make breakfast this morning, I saw her peeking out, and brought her a piece of lettuce as a special treat. But, when I got close to her, I noticed she was kind of wheezing -making a whistling noise with each breath. She did come out, came all the way over to her feeding station, ate some lettuce, but apparently went back to bed in short order. I decided to weigh, measure and photograph her and she was already back in bed, but I pulled her out, and when I picked her up to weight, she made a kind of muffled coughing noise. I'm very worried about pneumonia, thinking maybe I should have my sister bring her into the vet for antibiotics, but I wanted to see if anyone here had any ideas first.
