My cat vomited, not eating or drinking after food change. Vet?

I doubt very much that the litter change had anything to do with the signs you are currently seeing in Misu. Lack of appetite and not drinking water are both serious problems that could be caused by pain, nausea, internal organ problems (like kidneys or liver), or intestinal issues. Unfortunately these are very vague signs and he will need some tests, like bloodwork, urinalysis, and possibly x-rays to determine what is going on, and how to treat it. I urge you to call again and make an urgent appointment, or take him on to see an emergency veterinarian tonight.

Poor Ellie! I see that she isn't spayed. When cats aren't spayed, they can be prone to a life threatening infection of the uterus called a pyometra. This would cause her to vomit, not eat, and not drink. Other causes include a severe GI illness, eating something rotten, pancreatitis, or a foreign body. Given the risk of a pyometra and the fact that she isn't eating, drinking, and keeps vomiting, my recommendation is to have Ellie seen by a vet immediately. The vet can do a physical exam, blood tests, a urinalysis, and possibly x-rays to diagnose what is causing her symptoms so she can be treated. She likely needs a shot to stop the vomiting, and IV fluids for hydration along with any other treatment the vet deems necessary. If she does have a pyometra, spaying her is one of the recommended treatments. Please take her into a vet ASAP.

It sounds as Mukie is suffering from a gastrointestinal condition, possibly an infection. it could also be due to ingestion of a foreign body material. i would recommend taking her to the vet the first chance you get, she will need to be checked first, if the vet thinks it's a simple gastrointestinal infection she will need an anti vomiting injection, antibiotics and a special food for a few days in order to get better. if the vet thinks it is more serious she will need a blood test and possibly an ultrasound in order to find out what is wrong.

Hello, sorry to hear about Mitzi. It certainly sounds like he may be having early signs of becoming sick. In kittens we would be concerned with respiratory infections, GI infections with parasites, or viral infections. You could certainly watch him for a couple of days to see how he progresses, being that he may bounce back on his own. However, if you note any vomiting, diarrhea, coughing, or sneezing then you should have Mitzi evaluated. Hope this helps and best of luck.

Poor Willie! Given that it appears she has vomited a foreign object (decorative balls from your bedspread) and the face she isn't eating, I would take her into a vet now. It's actually very serious when a cat doesn't eat, as they will develop a fatty liver when they go too long without eating. A fatty liver is fatal without treatment, so that needs to be avoided. She may need x-rays to determine if she has any more of those balls in her GI tract. Please take her into a vet now. Best of luck, I hope this helps!

Poor kitty! If she is vomiting and not eating or drinking, this is a serious problem - even if the problem began because of stress, she will quickly become dehydrated if this continues. I would recommend having her examined by a vet as soon as you can - he/she can do blood work and x-rays if needed to find out what's wrong and get her started on IV fluids and other supportive care if needed.

Poor Tomasina. It's actually very serious when a cat won't eat, as if they go long enough without eating (about 72 hours), they will develop a fatty liver. A fatty liver is fatal without treatment, so you want to avoid that. I'd have her checked out by a vet today. While the change in diet can cause stomach upset in the form of vomiting and loss of appetite, it could also be she is sick.
