Some cats have a dysfunctional immune system that identifies normal food molecules as allergens. Meats like chicken, beef and pork are one of the most common causes of allergies in cats.

An older cat with food allergies will experience symptoms of sensitive stomach, combined with symptoms of allergies. These cats usually have itchy skin, frequent loose stools and will vomit after eating.

Food Intolerance

Intolerance towards food should not be confused with food allergies. With food allergies, stomach sensitivity is caused by the immune system’s response to an allergen from food.

With food intolerance, the food isn’t properly digested. So nutrients aren’t properly absorbed into the bloodstream. This means that the food will pass through the stomach and out through the stool in an almost unchanged state.

Diseases and Intestinal Parasites

Diseases of the pancreas, liver or gallbladder can lead to improper digestion and cause a sensitive stomach.

Intestinal parasites prevent proper nutrient and water absorption. This results in an upset stomach. Intestinal parasites also cause frequent watery stools.

Hairball Production

Cats are meticulous groomers. But if your cat also sheds a lot, then the risk of developing hairballs increases.

Hairballs can affect the way stomach digests food. To re-establish functionality, the stomach will try to pass the hairball through the gut or through the mouth. In most cases, regurgitation is an easier option.

Feeding Behavior

While some cats are fussy eaters, others will eat everything that moves.

Eating mice and other rodents that roam outdoors can cause stomach sensitivity. These animals are also exposed to possible contaminant or diseases and are certainly not the best food for older cats with sensitive stomachs.

Change in Diet

A sudden change in brand or type of cat food can cause stomach sensitivity. When you replace your cat’s food with a new one overnight, you shock the whole digestive system.

Changing your cat’s food from time to time isn’t a bad thing. However, start slowly and give your cat at least a one week adjustment period.

Stop Feeding Inappropriate Food

Generally, this depends on the individual sensitivities of each cat. To start with, you should avoid unnecessary foods like cat treats in your cat’s diet. This will help narrow down the list of foods that might be causing your cat’s sensitivities.

The most common problem causing foods for older cats with a sensitive stomach are:

  • Dairy Products: The lactose found in dairy products like cow’s milk and cheese can’t be properly digested by cats. Try lactose free milk.
  • Beef: It’s still unclear why some cats have trouble digesting beef. Besides being one of the more common food allergens, beef also causes diarrhea in many older cats.
  • Fat Trimmings: Due to the large amounts of bile necessary to break down fats, too much of it in the cat’s diet is bad. If there isn’t enough bile, the undigested fat will be passed as diarrhea. In some cases, the undigested fat will be vomited out.
  • Grains: Cats are natural born carnivores. Thus, their digestive systems aren’t built to digest and absorb grains. You should avoid foods, especially ones that contain soy, corn or wheat.
  • Additives: Some commercially made foods contain many additives. Hence, it becomes impossible to pinpoint the one that is causing your cat’s sensitive stomach. Try to pick a food that doesn’t contain additives, artificial colors, flavors and preservatives.
