My cat has hyperthyroidism symptoms & won't eat. When to see vet?

This is concerning that you can't get Lissy to eat anything, and I would take her into a vet immediately. It could be that she isn't one the correct dose of thyroid medication or there is another medical problem going on with her. Leaving cats who aren't eating is very dangerous, as if they don't eat going on 72 hours, they develop a fatty liver which is fatal without treatment. The vet can give her an appetite stimulant, and can diagnose why she isn't eating. Please take her into a vet right away. I hope this helps!

Since it has been several months since her last bloodwork was done I would recommend bringing her in if this change in behavior is lasting longer than a few days and there haven't been any other changes in the household that would be causing her anxiety (such as new pets, people, etc.).

I'm so sorry that Cleo is having these problems. Since you mentioned that she is hyperthyroid, I would be sure to check her thyroid level and her blood pressure. If either is high, it could be responsible for the behavioral changes that you are noticing. I would also recommend checking a urine sample since urinary tract infections are common in older female cats to make sure that isn't playing a role in her sudden changes. Cleo is certainly an older girl and not eating as much is certainly a worrying sign, but I would make sure there isn't any treatable explanation for her recent behavioral changes. Good luck! I hope that was helpful and answered your questions. Thanks for using Petco Pet Education Center, formerly Petcoach.

I suspect Cleo is not feeling well and may be nauseous. Just like people, there are many conditions that can make pets feel sick. This could range from bacterial over growth to intestinal blockage. Also like us, diseases are best addressed early and this may result in a better prognosis. You need to monitor Cleo closely. If she is not eating or drinking well for 24 hours, if there is vomiting/diarrhea/coughing or signs of pain, I recommend to have her examined by the veterinarian today. If the lethargy lasts for 24 hours, your kitty also needs to be examined. 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. At home, Cleo should continue resting. Encourage eating and drinking. Bring her the food and water. Fluid intake is very important when pets and people don't feel good. You may try offering her some boiled white meat chicken or canned tuna (in water not oil). Hopefully this will pass quickly. I hope Cleo starts feeling better quickly! Please feel free to post any additional questions.

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.

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).

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.
