If it worries you and you feel that your tort is not getting better go to a Vet for a check up. Blood testing and an xray probably will give enough info to see what is going on.He is also almost constantly doing what looks to be attempting to defecate (pulling head in shell, eyes swelling, legs pulling in). I have been treating him for constipation but am worried it is something else. I was going to take him to the vet but he was just there and got a clear bill of health so I am not sure if that would be helpful. Could it be a urate stone? If so how could I tell?
