Kitten won't eat after food changes. Could it be an upset stomach?

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.

Mitzi does sound quite sick, and I'm concerned that she has not eaten or drank today. It's actually very serious when a cat won't eat, as they will develop a fatty liver if they go too long without eating. While a sudden switch in diet can lead to GI problems, it shouldn't cause her to not drink. I would take her into a vet immediately to get checked out. Best of luck.

It sounds like Akira may be sick, and it is very serious when a cat won't eat. If they go long enough without eating (around 72 hours), they will develop a fatty liver. A fatty liver is fatal without treatment, so you want to avoid this. Have her seen by a vet first thing in the morning.

A sudden change of food will cause GI upset in cats, which is what it sounds like is happening with Jericho. When you do a sudden change in food, it's recommended to do it slowly. Because she is still occasionally vomiting, I would try a home remedy to see if that settles her stomach. I recommend withholding food for 12-24 hours, then feeding a bland diet of boiled white meat chicken (no bones) in small amounts several times a day for a couple of days. Then slowly add back in her normal diet. If the vomiting continues in the absence of food, she vomits the bland diet, develops diarrhea, stops drinking water, starts vomiting water, or becomes very lethargic, she will need to see a vet right away.

I would continue to monitor Cleo and maybe offer her some tuna and white rice to help settle her stomach. If she goes more than 24 hrs without eating or seems to get worse st any point then it's best to take her to your vet for evaluation and treatment depending on the underlying cause. She could have eaten something that upset her stomach or have an internal illness that is found out through diagnostic testing (bloodwork, radiographs, etc). I hope that she feels better soon and is able to make a full recovery. Best wishes and take care.

Hi there! I'm glad to see that Artemis is doing a little bit better. You may not see feces in the litter box for a few days after she starts to eat again, so I wouldn't be too worried about that. I'd watch her when she goes to the bathroom and look for any straining or discomfort, that may indicate that maybe she does have diarrhea, or even constipation. I usually will encourage owners to try a variety of foods for a cat that isn't eating. As long as there isn't a specific reason your veterinarian recommends baby food only, I would try brands like weruva (especially the seafood bits - for some reason I see cats that refuse just about everything eat that), and tiki cat. They are usually very palatable. The only thing you can really do is keep trying different foods. If your veterinarian hasn't prescribed anything yet, there are a few medications for cats that can help with appetite stimulation. Sometimes too, if it's a multiple cat household, if the ill cat isn't that attached to the other cats, and essentially just coexists, I recommend giving the ill cat some time for itself. Maybe set him up in his own area where he has his own litter box, and maybe a feliway diffuser, some rescue remedy, and/or catnip. Offer him fresh portions of a variety of foods a few times a day. Maybe that will help. From what it sounds like you're doing a great job. A cat that stops eating is always a very difficult patient, so kudos to you! I hope you find this answer helpful! Best of luck!

It's now a medical emergency that Bunty hasn't eaten in 18 hours. If she goes much longer without eating, she will develop a fatty liver which is fatal without treatment. She is quite sick and cannot be treated at home. Please take her into a vet immediately. Best of luck.
