I don't no what went wrong but Tank has not pooped in over 2 weeks. I feed him a good diet and temps are fine. I have never had this happen before. I have been trying everything and decided to make the 1 1/2 hour drive to the vet tomorrow. He has been trying to go and makes a straining noise but nothing. I stopped feeding dry hay and have been feeding him greens, fresh wheat grass, cactus and pumpkin for a week. I have been giving him long soaks every day. When I take him to the vet is there any advise on what to let them do and what to say no to?? The visit is $70 and ex-rays are $150 but they are the only choice I have.
