My cat hasn't eaten in 3 days and is lethargic. What's wrong?

It sounds like poor Samba isn't feeling well, and he has to see a vet immediately. When a cat doesn't eat going on 72 hours, they develop a fatty liver which is fatal without treatment. This absolutely needs to be avoided, which is why he has to see a vet right away. Anorexia is a very general sign of illness, and it could be caused by many things such as dental problems, GI obstruction, systemic illness, kidney disease, heart disease, liver disease, infection, injury, or cancer for example. The vet can diagnose what is causing the anorexia and can treat him for it. Please take him into a vet now. I hope this helps, good luck!

Vomit is a symptoms usually referred to a problem located in the gastrointestinal system. It can be secondary to a dietary indiscretion. It could be caused by a stomach inflammation (gastritis) or if he is having soft feaces as well can be an upset of the whole gastrointestinal system. Pancreatitis might be another option and cannot be ruled out at this stage. Vomit can also be a secondary to systemic diseases (i.e. renal failure). If it's already 3 days and not improving I recommend a consultation with your veterinarian asap for a full health check. Bobo is not drinking therefore he might be dehydrated and possibly need hospitalization and fluidotherapy to restore the fluid losses. Please post again in the forum if you would like to discuss it further. I hope this answer was helpful.

I am sorry to hear Pistol Pete isn't feeling well. It sounds like he is painful somewhere. I recommend taking him to the vet ASAP to determine why he isn't eating or drinking. Cats can only go about 3 days without eating before they get much worse. They may need to run some blood work and xrays to determine why he isn't feeling well. Good luck and kisses to Pete!

Mr. Peabody seems to be experiencing very general symptoms of illness, meaning this could be pretty much any disease. when cats behave this way it's usually because they feel very ill or are painful, and it's usually a sign of a serious condition. i strongly recommend that you take him to the vet in order to get it checked and treated ASAP.

Poor Moe! From what you're describing here, I'm afraid he sounds quite sick. Vomiting, not eating, and acting lethargic are always very concerning symptoms, especially since he's been sick for 2-3 days now and seems to be getting worse. Unfortunately, these are very vague symptoms that could be caused by almost any kind of illness, so it's hard to say what might be wrong without being able to examine him and run some tests. I do think that this sounds like a serious, potentially life-threatening problem that shouldn't wait until tomorrow, so I would recommend taking him to an emergency clinic today to be seen. If you're not sure where to go, try calling your regular vet's office - their voicemail message should have contact information for your nearest ER or an on-call doctor for emergencies.

Tommy is experiencing very general symptoms of disease, these symptoms could fit almost any internal condition, maybe he is suffering from nausea due to a gastrointestinal disease and maybe he is in pain, from the symptoms described it's very hard to know. i would recommend taking him to the vet as soon as possible in order to get him checked, if he doesn't show any other obvious symptoms during the examination, a blood test and possibly an ultrasound will be needed in order to try and find out what is wrong with Tommy.

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Kong. When a cat doesn't eat, it's extremely serious. That's because if the cat goes long enough without eating (about 72 hours), they will develop a fatty liver. A fatty liver is fatal without treatment. The fact that he won't eat or use the litter box tells me he is quite sick or injured. I would consider his symptoms a medical emergency that cannot be treat at home. Please take him into a vet immediately. Best of luck.
