Why is my cat suddenly not eating, losing weight, and lethargic?

Poor Mickey! It definitely sounds like he is feeling terrible. Just like people, there are many conditions that can make pets feel sick. This could range from parasites to cancer. Also like us, diseases are best addressed early and this may result in a better prognosis. I recommend to have him examined by the veterinarian today. The doctor will need to learn the underlying cause in order to give appropriate treatment. Bring in a stool sample in case the doctor needs to test it. The doctor will likely want to check the thyroid, kidney and blood sugar levels to looks for evidence of renal disease, hyperthyroidism or diabetes since these three conditions will all cause weight loss. A physical exam is the only way to start narrowing down the causes. I hope Mickey starts feeling better quickly! Please feel free to post any additional questions!

The type of symptoms you are reporting combined with Keaca's age is definitely a cause for concern. While lethargy and anorexia are very non-specific symptoms, there are definitely a couple of conditions that come to mind (particularly in an overweight cat). Some of the things I would think of include liver or kidney issues, pancreatitis, diabetes, and certain types of cancer involving the gastrointestinal tract. I think a good start to find out what may or may not be wrong would be to take Keaca in for a physical exam and to have some baseline blood work obtained. This will provide you with some information to rule out several of the conditions I mentioned above. If they are not able to make any determination from that information, some diagnostic imaging may be indicated (x-rays or ultrasound). Hope this helps and that Keaca is feeling better soon!

There are three very common diseases that older cats get and I am guessing she has one of these that are causing her symptoms. Hyperthyroidism Diabetes Kidney disease These can all be easily tested with some simple bloodwork at your vets. It is not likely parasites so spend your money on the blood testing and not the fecal test. Only do the fecal test if the blood work all comes back normal. My best guess as to what is going on based on your description would be hyperthyroidism which can be easily treated. So please get Ebony to your vet for an exam and testing.

I believe these very general symptoms are very worrying, i cannot tell you what is the cause as there are many options but i strongly advise that you take him to the vet urgently to have a blood test done and get this checked.

I'm sorry to hear that Nanking has not been feeling well. A sudden loss of appetite with noticeable weight loss are quite concerning and could be due to a wide variety of conditions, including hyperthyroidism, kidney disease, inflammatory bowel disease, pancreatitis, among others. Parasites seem less likely for such a sudden change, but are certainly possible as well. Your best bet is to take Nanking to the vet for an exam and diagnostic testing so that the cause of her issues can be determined, as this will provide a more accurate prognosis for her condition. I hope that all goes well!

I definitely think you should have Dahlia examined by your veterinarian. A few diseases that could cause an increased appetite with weight loss include intestinal parasites, diabetes, and hyperthyroidism. Your vet can examine Dahlia and her stool, and may recommend checking lab work if parasites seem unlikely. All of these diseases are very treatable, but it's important to get a diagnosis quickly.

In an older cat, my first thought would be dental disease. This would be painful for Krinkle, cause him to eat less, and subsequent weight loss. It could also be that he has diabetes, kidney failure, or hyperthyroidism. Having him seen by a vet this week is a good idea. I hope this helps!
