My cat has diarrhea, vomiting, and is tired. When to see a vet?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Male | unneutered | 2 years and 2 months old

My cat is 2, half Persian and he does not go outside or associate with other animals. He’s had diarrhoea over the past two weeks but not every day, and he threw up a few times one day last week. He’s still eating but we are feeding him less and only dry food. He seems tired but still plays, and shows no signs of pain when I press on his stomach. What should I do?

I would recommend that you have Alfie examined by a veterinarian. His symptoms could be caused by food intolerance, food allergies, intestinal parasites, inflammatory bowel disease, intestinal lymphoma, hyperthyroidism, systemic disease (liver, kidney, pancreas, diabetes), among others. After a thorough physical exam and review of his history, the vet may recommend bloodwork, intestinal parasite screening, or ultrasound to determine what could be the cause. They may also recommend that you do food trial for possible food allergies.
