My old cat is not eating, losing weight, and very lazy. What's wrong?

Updated On September 23rd, 2025

hello, what should I do, my cat is 12 and is not eating much, losing weight, he's becoming very lazy and just isn't himself. he is beginning to stop meowing and completely becoming to look very old and kind of sad. I don't know if it is anything to do with a tick we found on his leg on Thursday (17/5/18). Can you help?

I believe these very general symptoms are very worrying, i cannot tell you what is the cause as there are many options but i strongly advise that you take him to the vet urgently to have a blood test done and get this checked.

    He really needs to be examined by a vet for a work-up to determine the cause. He could have an infection, parasites, kidney disease, liver disease, diabetes, hyperthyroid, etc. Your vet can run blood work and take an x-ray, if needed, to help diagnose and then determine the best way to treat.

    Cats tend to deteriorate quickly, so I would recommend a veterinary visit. Starting with blood work which will include a cell count, an evaluation of organ function and a thyroid evaluation should help your veterinarian to find what the source is. Cats can develop Hepatic Lipidosis or a fatty liver after a few days of not eating, and this can be difficult to reverse. I would bring him in today if possible.
