My gp had bladder stone surgery 3 weeks ago, he is around 18 months old. He recovered well from the surgery and is now off all meds except Cystophan. He had Baytril as well. Yesterday I noticed he hadn't pooped as much as usual but back to normal.today. I've noticed he is squeaking when he poops as if in pain. It surely can't be another stone this quickly? Taking him to vet tomorrow. Does anyone have any ideas or experience with similar? Thank you.
