My 12-year-old cat is losing weight but acting normal. Is this okay?

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.

Hi there. You're correct that being able to feel the backbone or hip bones more easily than normal when petting your cat is a common early sign of weight loss. This could be caused by a number of different things - she may have some type of infection, a systemic illness like liver or kidney disease, or a GI problem like inflammatory bowel disease or chronic pancreatitis (weight loss can be the only symptom of these issues, in some cats). I would recommend taking Narla back to the vet for another exam to discuss your concerns and see if she has lost weight since last time. Your veterinarian may recommend blood work, x-rays, or other testing if needed to help diagnose the problem.

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.

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. There is a lot that we cannot tell from an examination on a pet, especially if it is something like sudden weight loss but the pet is otherwise acting normal. I would recommend having Kini's blood tested to evaluate overall systemic functions and see if there is an explanation for the weight loss. Check thyroid level as well. If all is normal on blood but the weight continues to fall, I would recommend x-rays and an abdominal ultrasound. I hope this helps! Please let me know if you have any other questions or concerns and I would be more than happy to help you further.

Weight loss is possible due to increased activity, but 9kg to 4kg is more drastic than I would expect. I would discuss doing bloodwork with your vet. Increased activity and weight loss is common in cats with hyperthyroidism. Weight loss can also be caused by kidney disease and diabetes. All 3 of these conditions can be diagnosed with simple bloodwork (CBC, chemistry, thyroid panel) and urinalysis.

Unfortunately yes, weight loss and increased meowing can often be signs of illness in cats. You don't say how old your cat is, but if she is middle-aged or older the first thing I would be concerned about is possible thyroid disease - hyperthyroidism very commonly causes both of these symptoms. It also often causes increased appetite, and sometimes soft stool. Other possible causes could be diabetes, kidney disease, or even a digestive problem like inflammatory bowel disease. I would recommend having Ittybitty examined by a vet - he/she can do a simple blood panel to check for most of these problems, and advise you on treatment options based on the results.

The thyroid level can change in a month, especially if Dewey’s previous thyroid level was towards the middle of the normal range. There are also some other more specific tests that can be positive before the total thyroid hormone level increases. A few other diseases that can cause weight loss with a normal appetite include intestinal parasites, diabetes or occasionally certain types of cancer. If Dewey is continuing to lose weight I would recommend rechecking with your vet.
