My cat with a thyroid condition isn't eating now. Is this serious?

I'm sorry to hear that Cleo isn't eating as well as she normal does. Hyperthyroidism typically causes weight loss despite an increase in appetite, although rare cats may experience a decreased appetite. The change in Cleo's appetite alone may or may not be associated with hyperthyroidism. Other causes of this sudden lack of interest in food and lethargy could be related to a gastrointestinal virus, kidney disease, parasites, liver disease, among many other conditions. If she still isn't eating normally in the next day or two, Cleo should go to her vet for evaluation and likely blood testing. However, if she becomes experiences extreme lethargy, experiences profuse vomiting or diarrhea, or will not drink water, Cleo should go to the vet immediately. I hope this helps and that Cleo feels better soon!

Hello, sorry to hear about Lir. It sounds like she could be suffering from unregulated hyperthyroidism if her Vidalta is not having a good effect or she could be dealing with underlying kidney disease. If she continues to be inappetent or develops vomiting, diarrhea, and severe lethargy then she may need to be evaluated by her veterinarian again. This to have repeat bloodwork and make sure that her hyperthyroidism is well regulated and that she does not have underlying kidney disease. Hope this helps and best of luck.

Congrats on your new kitten, but I'm sorry Eloise isn't doing well. Yes, I would be very concerned that she isn't eating. When cats do not eat going on 72 hours, they develop a fatty liver. A fatty liver is fatal without treatment, so anorexia in cats is considered serious. While bringing home a new cat is stressful for the existing cat, it typically does not cause severe lethargy and anorexia. I would be concerned that Eloise is sick, and I would take her into a vet today for a health check. I hope this helps!

Poor Patches! It does sound like she's extremely sick. I would recommend taking her to an emergency vet tonight if you are able to, since it may not be safe to wait until morning if she is having bloody diarrhea and hasn't eaten in two days. The vet there can do blood work or other testing if needed to help determine what needs to be done. She may need to have her thyroid medication adjusted, or she may have some other problem such as diabetes or kidney failure that will need to be treated as well.

It's actually very serious when a cat won't eat. If they go long enough without eating, they will develop a fatty liver. A fatty liver is fatal without treatment. You need to take Tabitha into a vet now to diagnose what is causing her symptoms.

It's actually a medical emergency when cats do not eat. If they go long enough without eating, they develop a fatty liver which is fatal without treatment. Flora could have a severe dental problem preventing her from eating. Please take her into a vet now.

Poor girl. Cats typically recover from sedation within 12-24 hrs. Also they generally will still want to eat, even if its just a little bit. Try offering her some canned cat food or canned tuna to try an entice her to eat. If she got fluids yesterday, then she likely isn't thirsty yet. If she isn't herself by tomorrow, then its best to have her re-examined by your vet or get a second opinion. Her thyroid condition alone should not cause her to be quite this ill, so there may be something else going on here. I do hope that Meg is able to return to normal soon! Best wishes and take care.
