Why is my 11-year-old cat always hungry, meowing, and pulling fur?

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).

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.

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.

Thanks for using Petco Pet Education Center, formerly Petcoach! I'm sorry to hear Cow is having issues. As cats age, they can develop a variety of metabolic issues, including an overactive thyroid, diabetes, and kidney disease, among others. These can lead to appetite changes, as well as fur changes. I would recommend Cow be evaluated by his regular veterinarian, have any necessary testing done (bloodwork, skin evaluation) and start any medications that may be needed. Good luck!

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 :)

Hello sorry to hear about Norman. The behavioral changes, the weight loss, and unkempt coat are all signs of hyperthyroidism. If you are also seeing a ravenous appetite (hence the hunting) and increased drinking and urination they may also fit with hyperthyroidism. The only way to know is to test his blood and measure the levels of thyroid hormone. In the mean time, ensure he has adequate access to water and food until you are able to take him to your veterinarian. Hope this helps and best of luck!
