Why is my senior cat not eating, losing weight, and making clicking sounds?

Updated On September 23rd, 2025

Pet's info: Cat | British Shorthair | Male | neutered

Hi my cat is around 19 years old and has been off his food recently (for around a wee maybe morek) he has been having half a tin over two days. He makes a loud clicking noise when he does eat. And over the past couple of months has lost rather a lot of weight. He really doesn't seem himself. We have a vets app scheduled for Wednesday however we were just hoping for some advice to hopefully put our minds at rest as we are very worried. He also had diarrhoea about two days ago.

With the symptoms you are describing I tend to test for advanced kidney disease or hyperthyroidism. I would encourage him to eat as best you can and get him to a veterinarian. With blood work and a urinalysis they should be able to give you a diagnosis and help direct you as to what is next

    I would recommend that you have him examined by a vet to see why the change in appetite and weight loss. 21 is quite old for a cat, and they can have several issues that could cause his symptoms. Blood work to check out liver, kidneys, and thyroid levels would be indicated.
