The cat was with 2 others before my dad took him in at age 4. He has had enemas. Struggles with constipation. Vet said he has megacolon. Takes lactulose. I feel he is allergic to catfood he was put on to help with his bowel royal canine high fiber. Will vomit and scratches his head so ends up getting allergy injections every 6 weeks. Any suggestions for another type of food? I need something to help with megacolon/constipation that he won't be allergic to.
Thanks
