Concerned that your cat is not eating? It can be hard to tell a picky eating episode from a serious health issue. A change in your cat's routine is a concern, but figuring out the cause is the first step to getting your cat eating again.
Why Isn't My Cat Eating?
Truth: Your cat loves to eat. It's up there in her favorite activities, along with sleeping, playing and trying to get her pet parents' attention. But eating is also a basic element of survival, without which your cat's health may rapidly decline.

Changes in Food
Cats are creatures of habit and will typically resist change, especially to their meal plans. Have you recently changed your cat's food? Maybe they are stubbornly refusing to try the new flavor. Cats can take a while to accept new foods, so a slow transition is generally recommended. Your kitty can't go too long without eating, so they don’t eat for 24 hr even after offering the old food again, s it's time to explore other possibilities for why she isn't eating.
Changes in Environment
Your cat's stubbornness can pop up if they are unhappy with the surroundings. "Cats may also go on brief hunger strikes in response to environmental stressors, such as the presence of guests in your home," points out Animal Planet. Other environmental changes, such as moving to a new home or adding a new pet or baby to the mix, may affect eating habits, too. If you know these types of things stress your cat, talk to your veterinarian about ways to help your cat relax.
Possible Illness
Digestive issues, such as constipation, colitis and inflammatory bowel disease (or chronic inflammatory enteropathy), are stressful on your cat's body, leading to loss of appetite, gas, vomiting and diarrhea. Other underlying illnesses that may affect appetite include kidney disease and dental problems. Banfield Pet Hospital explains that oral problems, like dental disease, oral tumors, infections or injuries, that make chewing difficult or uncomfortable could cause your cat to stop eating. Be sure your veterinarian includes a comprehensive dental exam during every checkup.
Because only a vet can diagnose an illness, contact your vet's office right away with any unusual or significant health changes. You should also take your cat in for a dental checkup if refusing dry food or favoring one side of the mouth when chewing.
