At EasyPet, we are committed to presenting the most accurate and up-to-date information to assist you in your pet care journey. When appropriate, we consult licensed and practicing veterinarians to fact-check our professionally written articles.

Let’s face it, we love our pets, especially our cats. They offer us an endless supply of companionship and entertainment. They can make even the darkest of days seem brighter with just a nuzzle of your hand or a slow rub up against your ankle. We often wonder what we would ever do without them.

With that in mind, it is perhaps one of the greatest challenges of cat ownership to see your favorite feline struggling with a health issue. One of the more difficult ailments to deal with is a sensitive stomach, which can often result in additional symptoms such as diarrhea.

This type of issue is often the result of hyper-sensitivity to many of the mainstream ingredients in today’s cat food. If you have a cat that struggles with a sensitive stomach or issues with diarrhea then read on to get helpful information on the causes of these issues and the best cat food alternatives to help with your kitty’s upset tummy.

What is the Best Cat Food for Sensitive Stomachs?

What are the Symptoms to Look for?

Your first clue that your cat has sensitive stomach issues is most likely going to occur when you clean out the litter box. If you notice loose stools and/or an increased volume of feces in the litter box then it is very likely that your cat has an upset tummy.

Diarrhea is not a common occurrence for a healthy cat so if you see evidence of it then it is certainly worth investigating. The first step in that process is to try to gauge the frequency and intensity of your cat’s diarrhea. Now, unless you routinely hang out near the litter box, this is not as easy as it sounds. However, if you are diligently cleaning out the litter box then you should be able to determine when any symptoms of diarrhea started to occur.

This is an important factor because it allows you to quickly gauge the severity of the issue. If the duration of the diarrhea issue is relatively short, then it was most likely caused by something your cat ate or drank. The issue should go away as soon as your cat passes the guilty substance out of its system.

If the diarrhea is persistent it could be considered chronic. This means that the symptoms have been occurring consistently over the course of several weeks. This may point to a consistent cause such as an allergic reaction to your cat’s regular diet.

If the symptoms seem to start and stop, meaning they are intermittent, then it may be more difficult to determine the culprit. It could be an allergic reaction to its normal diet or it could be the fact that the neighbor’s kid is feeding it bowls of milk every now and then. You may not know that giving your cat the milk that you drink can routinely cause diarrhea.

One last symptom to look for in the litter box is the presence of blood in the stool. As you can imagine, this should be considered a serious issue and be dealt with accordingly.

Here are some other indicators that your cat may be suffering from sensitive stomach issues or diarrhea. These won’t require you looking in the litter box.

  • Vomiting
  • Pain
  • Pale or yellow colored gums
  • Sluggish actions or a depressed mood
  • Fever
  • Dehydration

What are the Potential Causes?

One common cause for the onset of diarrhea is a sudden change in your cat’s diet. If you have recently decided to try a different cat food, your pet may take a while to adjust to it. Sometimes you have to change because you don’t have time to swing by the specialty food store and ended up picking up a small bag at the convenience store to tide your kitty over.

Perhaps, you just couldn’t pass up the lower price on a different brand at the supermarket. Whatever the reason for the switch, you need to be mindful that it can upset your cat’s digestion. Your pet will adjust and should get back to normal litter box duties fairly quickly.

Another potential culprit is that your cat got a hold of some spoiled food. Whether it was foraging around outside or found some human food up on the counter, it is possible that your cat just ate some bad food. Just like you, this will cause some discomfort for a period of time but should subside.

If your cat is on any prescribed medications it is possible that it could cause a side effect such as diarrhea. These symptoms should be brief in nature as well and should not last any longer than the time that our cat is actually taking the antibiotics or other medications.

Hyper-sensitivity to the food you are feeding your cat could be the most likely issue. Many of the pet food brands on the market have a long list of ingredients. Some brands also contain a significant amount of wheat, gluten, and other by-products. Most pets, especially cats, will have trouble digesting these ingredients even if it doesn’t cause symptoms such as diarrhea.

Even if you are feeding your cat one of the all-natural pet foods, It is still possible that for your feline friend to have an allergic reaction. Many of these all natural foods will include fruits and vegetables such as apples, blueberries, pumpkin, and spinach. It could be that one or many of these ingredients is causing an allergic reaction that is affecting your cat’s digestive system.

When Should You Get Your Vet Involved?

If diarrhea is happening for more than 24 hours then it’s a good idea to get your cat in to see the vet. You will need to make sure you are armed with some details about the frequency, onset, and severity of the diarrhea. This will help our vet determine potential causes and treatment.

If you notice that your cat is refusing to eat or drink then a trip to the vet may be in order. In addition to losing strength from not eating, your cat can quickly become dehydrated. Dehydration is a serious issue for cats and can lead to a number of other serious health issues. For this reason, dehydration should never be ignored.

Cats with upset tummies may also experience a decrease in activity level or interest in engagement. You may be the proud owner of that cat that sits on the window sill all day so it may be tough to determine a reduction in activity. However, if your cat does not show any interest in engaging with you then you need to pay attention. Your pet may be quietly sending you a loud and clear message that their health is in danger.

Finally, if you notice that your cat is tender in the abdominal area then you may have a serious, possibly life-threatening issue on your hands. In this case, you should seek immediate veterinary care.

Potential Treatment Options

Your vet will most likely run a series of diagnostic tests on your cat to determine the cause of the diarrhea. One such test is to look for the existence of parasites, or worms, in your cat. You may or may not have noticed worms in the stool. The parasite test will help determine if worms are the cause of your cat’s intestinal issues. If so, then your cat will be treated with a de-wormer. You should begin to see improvements in your cat soon thereafter.

If your vet determines that your cat is experiencing hyper-sensitivity to its diet, then you will need to look for alternative pet foods to try to alleviate the issue. There are many hypoallergenic, limited ingredient foods on the market. The reason that a limited ingredient cat food is important is that it minimizes the number of potential allergens in your cat’s diet. Many of the mainstream cat foods have a wide variety of ingredients, any of which could be the reason why your kitty is struggling.

So if you find yourself in the market for a low ingredient, hypoallergenic cat food, here are four of the best options to choose from.
