Fatboy's weight will not necessarily effect how much feces he produces and producing more stool is not a bad thing. Given the history of slow bowel movements (most cats have 1 -2 bowel movements a day) and the fact that he has already been constipated, I recommend a diet change. There is a diet made by Royal Canin called Fiber Response and it's my #1 choice for cats who struggle with constipation. It has special ingredients that promote a softer and easier to pass stool as well as promoting gut motility. Most cats do not need additional supplementation although severely affected ones might. Talk to your vet about using this diet. Your vet can then calculate how much to feed Fatboy to get him down to 13lbs. Continue to use the Miralax until you and the vet come up with a diet plan. Increasing the water intake can also help with constipation. You can do this by adding canned food with extra warm water added to his daily food intake. I hope this helps to point you in the right direction. Please post again with any additional questions.
