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).

Your cat has some very typical symptoms that makes me suspect of hyperthyroidism, although the age don't quite fit (usually starts at an older age). Other options are IBD, pancreatitis and lymphoma. You need to take Buddy to the vet in order to get checked and have a blood test done ASAP.

It could be more than one things but according to the symptoms i would say that my main suspicion would be hyperthyroidism, which is an hormonal disorder. this condition can be diagnose with a blood test and treatment is usually very effective.

Why is my senior cat always hungry but losing weight? Hyperthyroidism?

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.

Why is my senior cat losing weight, always hungry, and has diarrhea?

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

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

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

Training & Behavior

My cat is meowing loudly, losing weight, and acting aggressive. Why?

These sudden changes in temperament and the weight loss are commonly due to an endocrine problem called hyperthyroidism. The thyroid starts working more than normal increasing the metabolism (that is the cause of the weight loss) and causing behavioural changes similar to what you described. A clinical examination at your local veterinarian is essential to confirm this clinical suspicion and treat appropriately. A blood test and urine analysis are needed.

Why is my senior cat losing weight, howling at night, and circling?

There are three very common things that cats get as they age: 1. diabetes, 2. kidney disease and 3. hyperthyroidism (high thyroid levels). All of these can be easily ruled in/out with simple blood/urine testing. I suggest you have Monty to the vet to discuss this.

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

Thank you for using Petco Pet Education Center, formerly Petcoach! The symptoms you describe may be indicative of hyperthyroidism or diabetes, both of which are fairly common in older cats. Tests such as thyroid hormone levels (T4 and free T4) can be performed to rule out hyperthyroidism and chronically elevated glucose levels would be determined with a fructosamine level test. These are done with a blood sample, but are not routinely performed. I would also be happy to look at any test results you have for Dylan and provide a second opinion.
