I have a cat suffering from Megacolin
My cat Nike is taking Lactulose and Laxatone and was prescribed Royal Canin Gastro intestinal fibre response food. This food actually works as far as making his stools soft enough so he can go. The last food prescribed by another vet did not work and he was in trouble again. Also since he had two enemas he limps a bit. I am not sure what happened during the procedure to make him have a permanent limp. They told me before the procedure that his bones looked good.
