1.3.10 Last month due to constipation problems I switched Luke from dry food to canned Wellness & canned w/d. I have never just left food out for him because my little dog would eat it (she loves cat food). I tried feeding him twice a day but he meowed, begged, followed me, & acted like he was really hungry so we're at 3x a day. Also I mix Laxatone in it. Because the canned food is so expensive, I might try gradually adding dry food... we'll see. Kay in NC
