My constipated cat is straining. Can he eat tuna with lactulose?

Updated On September 23rd, 2025

Pet's info: Cat | Maine Coon | Male | neutered | 7 lbs

Is tuna in oil a good diet for constipated cat on lactulose? He was released from vet 3 days ago (enemas & treatment) and not had BM, straining but not producing. Is very thin but eating well with 3 doses Lactalose daily.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Shadow! If he is straining and not producing stool he needs to be rechecked by your Vet. He may need another enema. I am glad he is eating. Tuna and tuna juice is just good for a treat it is not nutritionally balanced to be the primary diet for cats as it is lacking in very important amino acids. I recommend Royal Canin Fiber Response for constipated cat. The lactulose can be decreased on increased based on stool. I wish you and Shadow the best!
