My rescue cat hasn't eaten in 3 days. When should I call the vet?

I would get her in to see your vet as soon as possible. It is vital that cats eat because after only a few days of not eating they can suffer liver damage. Take the worms too to see if they can identify them. Your vet will do an exam and labwork and based on these results will be better able to tell you what is wrong and how best to treat it.

I am truly sorry for the loss of your friend. It is critical for Hazelanne to be physically examined by your veterinarian. Cats who do not eat for 2+ days are at risk of developing serious liver related disease that may require hospitalization and supportive care. She may need blood tests to assess major organ function, especially liver function. Abdominal x-rays or ultrasound may also be recommended to assess her liver size and architecture. You can try warming her food or mixing in baby food to stimulate the appetite, but if the anorexia persists, then a vet visit is strongly advised.

If Sepia seems really depressed and lethargic, or if she starts vomiting multiple times in one day, then she needs to see an emergency vet right away as this may be serious. Otherwise, if she continues to not want to eat much then she needs to be seen when you can get an appointment, and I would recommend full blood work and an abdominal xray or ultrasound. She could have kidney disease or some other kind of metabolic issue going on like hyperthyroidism or pancreatitis. She is a young kitty so hopefully it's nothing serious! I hope that helps and best of luck!

Any cat that is hiding and not eating is sick. She needs to see a vet ASAP. When cats don't eat for about 3 days their liver starts to mobilize fats for energy and this causes fatty liver disease. So, she may get fatty liver disease on top of already having another illness which will make her prognosis even worse. Please get her to a vet ASAP.

Your cat really needs to be seen by a veterinarian for proper diagnosis and treatment. She is likely dehydrated from not eating or drinking well and will require subcutaneous or intravenous fluids. Because she hasn't been eating, she is also at risk of developing a condition called hepatic lipodosis. This disease is the most common cause of metabolic liver failure. At home encourage your cat to eat by offering highly palatable food, such as fish-flavored canned cat food or Stage 1 strained chicken or turkey baby food (no onions or garlic). If necessary, gently open her mouth and place a small amount of moist food on her tongue. Watch to see if she swallows it. If she does, place a couple more dollops of food on her tongue, then encourage her to eat a bit on her own.

It’s a medical emergency when a cat won’t eat, and if they go longer than 72 hours without eating, they will develop a fatty liver. A fatty liver is fatal without treatment. Koko cannot wait until Monday to be seen, i strongly urge you to take him into an ER vet now.

Missy has to see a vet as soon as possible. When a cat doesn't eat for three days, they develop a fatty liver which is fatal without treatment. She needs to see a vet now to prevent that from happening. In a senior cat like Missy, her anorexia could be caused by kidney failure, cancer, diabetes, and liver failure among other causes. It's also serious that she hasn't used the litter box in two days. She needs a physical exam, geriatric blood panel, and urinalysis to diagnose what is causing her symptoms so she can be treated.
