This is an ongoing problem, he has been very slowly going downhill for several months, and I don't know what to do. It started this summer, he was just a little "off", not himself. You all know what I mean, when a pet just--isn't right. I just figured it was because of the heat. Well, when the weather cooled off and he wasn't getting better, I took him to a local vet. We don't really have any rabbit vets around here, the closest one is something like two hours away. Anyway, the vet I took him to did a fecal sample, said there was a lot of bacteria in his poo, and put him on antibiotics for a little over a week. He seemed to improve slightly while he was on the meds, but went back to being lethargic again after he finished them. Because of him not moving around much at all, he started to get too fat. So I (slightly) reduced his pellet ration. He started losing weight, rapidly enough that I brought his feed back to normal. Now, however, he is still losing weight, and has gotten to the point that I can easily feel his backbone and ribs. Some days it seems his appetite is fine, some days he hardly eats at all. He has no energy at all, he just sits in one corner of his cage all the time and does nothing. He doesn't even get up to greet me when I come in anymore. I am thinking of trying another vet in the area that seems to know a little more about rabbits. (The one I took Big Mama to seemed fairly knowledgable. But it will be a few days before I can get him anywhere,does this sound at all familiar to anyone? A friend of mine said maybe his thyroid isn't working right? Any help would be really, really great. I don't want to lose this guy, he is my giant teddy bear.
