Why isn't my 7-year-old cat eating after I brought him home?

It's actually quite serious that Tigger isn't eating. When cats go for 72 hours without eating, they develop a fatty liver. A fatty liver is fatal without treatment. While it could be he is stressed from the move to his new home, it could be a medical illness causing him to not eat. He should see a vet immediately for a health check to prevent him from developing a fatty liver. Best of luck.

Poor Cathy! Not eating is quite serious in cats, as when they go long enough without eating, they will develop a fatty liver. A fatty liver is fatal without treatment. She may not be eating because she has a dental problem, systemic illness, infection, inflammation, or injury. Please take her into a vet now. Best of luck.

Congrats on your new cat! You are correct that Oliver should stay inside for a while since he has moved to a new home, good on you for doing that! It is a little concerning that it's been 36 hours with no eating or going to the litter box, but moving into a new home is stressful. Because cats can develop a fatty liver when they haven't eaten for three days or more, which is fatal without treatment, I'm going to give you some things to try to tempt him to eat. You can soak his food in gently warmed low sodium beef or chicken broth, or soak it in tuna juice. You can also try offering him small amounts of boiled white meat chicken (no bones). If you can get him to eat, then he will use the litter box. Should he still not be eating in the morning, then I would take him into the vet for a health check just to be safe. Hopefully, however he will eat some of the tasty morsels I've suggested you give him :-)

Yes, it is likely that Jack is upset about the addition of the new kittens. Introducing a new cat into the house is very stressful for an existing cat, especially old cats. I would try to tempt him to eat by offering him small amounts of boiled white meat chicken (no bones), or soaking his food in tuna juice or low sodium gently warmed chicken or beef broth. If he still won't eat with these methods, or it's close to three days since he last ate, I would take him into a vet right away. When a cat doesn't eat for three days or more, they become prone to a fatty liver, which is serious.

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.

If Calliope is going outside, likely she is getting food from another source, such as another house. Frequently cats who go outdoors find other homes to go to where they get fed. I'd try keeping her indoors for a week or two, this way you can monitor her and see if she really isn't eating. If she doesn't eating for longer than 24 hours after keeping her indoors, then I would take her into a vet right away. When cats don't eat for at least 72 hours, they develop a fatty liver which is fatal without treatment. It's important to avoid this, which is why I recommend a vet visit after 24 hours of no eating. Best of luck, I hope this helps!

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.
