Why is my cat having morning diarrhea with blood in his stool?

Updated On September 23rd, 2025

Pet's info: Cat | Manx | Male | neutered | 3 years and 5 months old | 20 lbs

My 3 yr old manx has diarrhea only in the morning. I had given him ham. He eats tinned food for breakfast and raw low fat mince for dinner. He is eating and playing normally and is an indoor/outdoor cat. Outdoors 2-3 hours during the day. There was a small amount of blood in stool this morning.

I am very sorry to hear that Ludo is experiencing this issue, I am sure it is unsettling. From what you are describing, diarrhoea which becomes liquid and has fresh blood in it, it sounds as though Ludo has colitis, or inflammation of the last portion of the large intestines. There are several causes of colitis in cats, ranging from bacterial infections, parasite infestations, IBD, or ingestion of contaminated food. Since you have only noticed one such episode I would continue to monitor Ludo at home. Provide a bland diet of boiled boneless chicken breast and plenty of fresh water. If the episodes continue, if Ludo becomes depressed, passes large amounts of blood, vomits, or seems very uncomfortable take Ludo to see his vet. I hope this answer was helpful and more importantly that Ludo feels better soon. Warmest regards to you both.
