Why is my cat thin, eating lots, and losing hair with bald spots?

Cats that are losing weight despite eating often have a thyroid condition although there could be other reasons like diabetes or kidney disease which are also common. I suggest you have Simba to your vet for an exam and some blood testing.

Thank you for submitting your question regarding Jasper. I agree with the concerns for a thyroid disorder. I do recommend that he sees a veterinarian. Blood work and urine testing will likely be needed to reach a diagnosis. Hyperthyroidism and diabetes can both cause an increased appetite with weight loss. Unfortunately, there is not a good recommendation for at home care. I hope this information helps!

Older cats like your kitty often get an overactive thyroid which will show weight loss, a really fast heart rate, sometimes vomiting, and more vocalisation than usual. Some cats get skittish as well. Hyperthyroidism can actually cause heart problems and mask kidney disease. Hyperthyroidism is easily diagnosed with a clinical exam and a little blood test and there are various treatments available, varying from Methimazole transdermal ointment or tablets to slow down thyroid hormone production, surgery to remove the overactive thyroid gland or radiotherapy. If your kitty is suffering from hyperthyroidism your vet will discuss the various options. I suggest you make an appointment tomorrow.

Micky sounds sick, and I would take him back into the vet for a geriatric blood panel and urinalysis. He may have a serious illness like diabetes, kidney disease, hyperthyroidism, or cancer causing his symptoms.

IF she isn't eating properly and losing weight, there is definitely something wrong with her, if she eats the wet food with great appetite, then the dry food must be the issue and that could be either due to a teeth disease or a partial GI blockage. either way you need to take her to the vet ASAP, she will need to be checked, especially her mouth, if nothing unusual is found during the physical examination the next step will be a blood test to try and find out what is wrong.

If he seems to be losing weight, I would make sure her thyroid level was tested. If so, the skin could be due to an allergy or other skin condition. Thyroid level being high can cause skin and hair changes so I would first get this level checked out. As for the skin, you can use Douxo PS calm shampoo and mousse, both of which can be found online quite easily. I hope this helps guide you in the right direction! Please let me know if you have any other questions or concerns and I would be more than happy to help you further.

This can be a sign of a medical disease such as hyperthyroidism, which can be common in senior cats. I'd have Sweetie seen by a vet for this behavior. The vet can do a physical exam, geriatric blood panel, and urinalysis. I'd take him into a vet today if possible. Best of luck.
