Choosing the Best Sensitive Stomach Cat Food

If your cat is beginning to show signs of food sensitivity, you may feel a tad hopeless at first. Of course, it’s not easy to see your cat struggle to keep their food down or experience allergic symptoms. 

The reason behind your cat’s sensitive stomach could definitely boil down to their diet. The first point of action is to consult with your veterinarian – that way you can get down to the root cause of the digestive issues. 

Once you discover the underlying cause for stomach sensitivity, you can take the next step in determining the best cat food. If you have recently switched foods, consider if an abrupt change in diet might be the cause of vomiting or diarrhea. A change in your cat’s diet should be made by gradually mixing the new food with the current diet, increasing the amount of the new food and decreasing the amount of the old food, over the course of about a week.  

Keeping a ‘food log’ during this process helps keep track of any changes in reaction and gives a reference point to compare down the road.  Remember that even a new treat counts as a change in diet.

That’s why we have culminated our top considerations to factor in your decision-making before committing to food that could continue to cause more problems down the line.

Does it have Quality Ingredients?

As you look for cat food that will mix well with their sensitive tummy, the first thing you can look out for is the endorsement from The Association of American Feed Control Officials (AAFCO).

After that it’s about ensuring the ingredients are all-natural and free of artificial flavours and preservatives. The highest quantity of any ingredient should be animal protein, and ideally this should be from a single source instead of mixed. Try chicken, fish, beef, turkey, lamb or duck. Ultimately, the less ingredients there are, the less it will irritate your cat’s stomach. And that’s what we want to see!

Is it Digestible?

The easiest way to tell if cat food is digestible is to observe if it features probiotic supplements. This can aid in maintaining your cat’s GI tract health by encouraging the growth of ‘good’ bacteria in the gut.

Other digestive friendly ingredients include vitamins C and E which help to settle upset stomachs. And omega-6 fatty acids are helpful in promoting good coat and skin health at the same time.

What food should I avoid?

While evaluating your food choices or contemplating if you should add certain foods to their diet, this list is off limits for felines with sensitive stomachs:

  • Raw fish;
  • Chives and onions;
  • Fatty foods;
  • Grains;
  • Bones; and,
  • Dairy (most cats are lactose intolerant).

How are the Customer Reviews?

While every cat is different, you can still gage how well a product fares with most felines based on how positive the customer reviews are.

The best cat food to support those sensitive tummies is formulas that will aid with digestion. You need to look for food that:

  • Is not irritating. Look for food that contains botanical anti-inflammatories. Omega-3 and omega-6 fatty acids are especially helpful in this regard. 
  • Is high in pure, premium animal protein. Since cats are obligate carnivores, it’s much easier for them to digest animal protein. This includes organs and muscle meat, not by-products. 
  • Has supplemental fiber to assist with digestion, especially diarrhea symptoms. 
  • Is packed with prebiotics, probiotics and digestive enzymes. 
  • Has no artificial flavors, colors or preservatives. Aim for food labeled by the AAFCO for being nutritionally complete. 

Ultimately, your cat needs quality food that will comfort upset stomachs while providing the nutrients your cat needs to be healthy.

To help your cat’s sensitive stomach, there are ingredient dos and ingredient don’ts. If you’re trying to get your cat on a healthy path again, avoid feeding your cat the following: 

  • Meat such as beef, lamb and sometimes white fish can cause sensitivity issues in some cats.
  • Any diary, grains, soy or corn. 
  • Treats – at least for a while until your cat feels better. Or ask your vet for some treat recommendations that won’t irritate a sensitive stomach. 
  • Human food – it’s tempting to offer your cat pieces of your dinner, but it’s best to refrain from this in the meantime.

You can either source food that meets all of the needs mentioned above but in some instances, manufacturers will make food formulas to cats with sensitive stomachs. If you change to other named meat protein sources – this can also help your cat’s digestion. Diet is one of the main ways you can help your cat get on a better path. Your cat needs to eat, so feeding quality food that contains less ingredients will help their stomachs adjust in no time.

Even with good intentions, a sudden change in diet can still trigger stomach issues. If you’re trying to experiment with other food options, you need to tread with caution. Your cat already had some digestion sensitivity so they’re more vulnerable to it if you switch their diet too fast. 

Start by mixing around 25% of the new food with their old food and observe any progress. Ensure you feed them at the same times every day. Then if all goes well, after a few days incorporate up to 50% and so on. If the symptoms don’t improve or your cat’s sensitivity increases – consult your vet right away.

There are some tell-tale signs and symptoms you can keep watch for to see if your kitty is having tummy issues. Don’t jump to conclusions until checking with your vet. 

  • Constipation 
  • Diarrhea 
  • Vomiting 
  • Lethargy and weakness 
  • Smelly or loose stools 
  • Bloating and gas 
  • Unexplained weight loss

Sensitive stomach issues can be either acute or chronic. Acute symptoms will be more short-term and chronic symptoms will be brought on slowly and may last a while. Keep an eye on your cat and track the symptoms you’re noticing and how often they occur. Then talk to your vet.

As a pet owner, it can feel hopeless when your cat is suffering and throwing up after they eat what you’re putting in front of them. But fear not, there’s probably something happening in their digestive system. A couple of common reasons behind sudden nausea and stomach sensitivity could be: 

Food allergies or sensitivity  

Your cat may be having an allergic reaction to food. It could be due to a newly introduced food product or even food that they have been regularly eating. Allergies and intolerances can come out of the blue. Once you know the underlying cause of the allergy, you can better control what you’re feeding your cat to keep their tummy happy. 

Intestinal parasites 

A more common root of gastrointestinal problems, intestinal parasites occur from contaminated food, dirt, prey or even mother’s milk for kittens. 

Inflammatory bowel disease 

This is a potentially more harmful condition and it occurs when the mucus stomach lining changes your cat’s ability to digest some foods.

Diet may be one of the main things in your control to help your cat’s digestion issues. However, there are some other ways to help your cat heal besides quality food. 


Water and moisture rich food will help digestion, in addition to hydrating internal organs. Ensure your cat has access to plenty of water, either through a running source (such as a mini water fountain) or through a wet food intensive diet. 

Less treats 

We know – treating pets is a pet owner’s favorite pastime. But in this case, it could potentially harm your cat’s stomach more. Too many treats can quickly upset the stomach. That’s why treats should not ever make up more than 10% of a cat’s daily calorie intake. 

Reduce stress 

Just as stress contributes to a lot of health issues in humans, it can also exacerbate issues for cats. Maintain a quiet, relaxing atmosphere and don’t be too overbearing with your cat while they eat. And place their food in an area of the home that won’t cause them disturbance.
