Why is my senior cat constantly hungry and only eating wet food?

These are indeed an unusual set of symptoms, thyroid disease and diabetes would be the first suspects for a cat with increasing appetite and weight loss. A specialist ultrasound scan of the abdomen may be worth while to investigate difficulties with food digestion and absorption or even tumours using up the calories

When an senior cat is eating more frequently yet losing weight, this can be a sign of hyperthyroidism. With hyperthyroidism, the thyroid gland is secreting too much hormone which causes an increase in the pets metabolism and subsequent weight loss. Have your vet check Hopes T4 levels to see if she is hyperthyroid and in need of medication to help stabilize her hormones so that she doesn't continue to waste away. This is easily diagnosed and treated with medication (i.e. Methimazole). Your vet will also want to run baseline bloodwork on your pet to make sure no other disease processes are there.

There are two very common health issues in older cats that are known for causing a sudden increase in appetite like this: hyperthyroidism, and diabetes. I would definitely recommend taking Lucy to the vet for a check-up when you are able to - he/she can do blood work to check for these problems. If she does have one of these illnesses, they are normally very treatable with medication once a diagnosis is made :)

The main suspicion would be hyperthyroidism, he is showing all the symptoms, you need to take him to the vet ASAP in order to have a blood test done that should confirm this, then your vet can start him on a treatment for this condition (fully treatable).

Noah does need to be examined by the veterinarian and he will need bloodworm and a fecal exam at least. The main causes of these symptoms are hyperthyroidism, kidney disease, diabetes, severe dental disease or severe parasites. The mucus in the eyes and mouth may be unrelated to the other symptoms. It's possible his immune system is run down and so opportunistic infections are occurring. Don't wait to have him examined. All those conditions can be successfully cared for if treated early. I hope this helps and that Noah starts healing quickly.

It is fairly rare, but ask your veterinarian if your kitty may be suffering from Cushing's disease or liver disease. Also sometimes cats can still be hyperthyroid, even though the thyroid parameters are within normal limits (this is called euthyroid sick). He could also have a tumor. In any case, this needs to be investigated further.

As he is already 11 i would suspect a condition called hyperthyroidism, the main symptoms is constant hunger. you will need to take him to the vet to get it tested, a medical treatment is available for this condition.
