Putting your cat on a diarrhea diet

These are the 7 best cat foods for diarrhea from our side. Before selecting the best cat food for your cat, keep a few tips in mind. First of all, you should always keep your vet in the loop. According to most vets, you should not give any food to your cat for about 12 hours when they are suffering from digestive issues. Ask your vet if the same is the case with your cat.

When you start giving your cat new food, start with small portions. A sudden change to their diet might make diarrhea even more severe. You wouldn’t want that, right?

The biggest risk during diarrhea is dehydration. Make sure that you have a bowl full of water for your cat at all times. If you are feeding them dry food, serve it with water to add moisture to it. Always be gradual in any change that you bring into their diet. When the stool becomes firmer, you can switch back to the cat’s original diet but do it slowly. Start with small portions before serving the meal size all at once.

Buyer’s Guide

Even when you have a few good choices in front of you, it can be hard to choose the best dry cat food for diarrhea. When it comes to choosing the right option from the best options, you have to look at certain features.

It is important to remember that the first cat food you try might not suit your cat. Eventually, you would have to try other cat foods. Even when you are choosing the alternate options, you need to look for the following things:


Whenever you are buying cat food for cats with diarrhea, you need to make sure that it is rich in nutrients. Your cat is already losing a lot of moisture. The poor creature is unable to eat its regular food since its body is not able to digest anything. So, weight loss is inevitable. To counter this, you need to feed your cat a highly-nutritious diet. It is best if the diet is rich in protein and moisture. While the moisture tackles dehydration, the protein helps in building muscle mass.

It is better to go for cat foods that are low in carbs since your kitty would not be able to digest high carbs easily. If your cat is an indoor feline, it would not be able to digest carbs anyway. Also, carbohydrates can raise your cat’s sugar levels so it is best to steer clear of them.

If you do want to feed cat food with carbohydrates, look for carbs such as sweet potatoes and chickpeas. These are comparatively easier to digest for feline stomachs.


There are a few ingredients that you should specifically look for when you are buying food for your sick cat.

  • Proteins: Make sure that the proteins are naturally-sources. Most of the time, the proteins come from chicken, lamb, beef, salmon, sardines, duck, or muscles. If you can find a cat food that has additional proteins in the form of liver bits, you are in luck.
  • Greens: Your cat needs the greens just as much as you do. Most owners fail to provide micronutrients to their cats thinking that cats, being carnivores, do not require fruits and vegetables. This is not true. You should feed cat food to your cats that are rich in cranberries, apples, carrots, sweet potatoes, and berries.
  • Fats: Not all fats are fat. Learn this now and learn it for good. The best cat food for sensitive stomach diarrhea is the one that contains omega 3 fatty acids such as DHA and EPA or omega 6 fatty acids. Along with being nutritious for the body, these fatty acids also fight against inflammation.
  • Herbs: Even though this is not a must, it is good to have basil, kelp, rosemary, or other herbs in the cat food.

No Additives

If your cat is already sick, chances are that it would get even sicker if the cat food contains additives. When you are buying cat food, you should do your research well. Do not buy from companies that source their ingredients from Asian countries, especially China.

Do not feed your cat any food that contains:

  1. Artificial flavors
  2. Preservatives
  3. Hormones
  4. Antibiotics
  5. Rendered fat
  6. Un-natural meat

A rule of thumb is to only buy those cat foods that have lesser ingredients. The best companies know that they only need to include a few ingredients in the cat food for it to be the perfect nutrition for a feline. However, when you look at the products of shady companies, you will immediately see ingredients that you do not recognize or pronounce for that matter. Artificial ingredients or preservatives are detrimental to your cat’s health. Also, they can trigger health conditions in your cat and may even make diarrhea worse. If you see rendered fat in the ingredient list, run the other way.

Dry or Wet?

This is a choice that you would eventually have to make when buying cat food. If you ask different owners, they would have different opinions about what kind of food is the best. You must know your cat’s needs and buy the food accordingly. Some cats do quite well with dry food but others need wet food, especially if they are losing water due to a gastrointestinal problem.

Dry food is good for older cats as they are much experienced with eating on their own. This kind of food gives you the liberty to just lay out the dish and let your cat finish it up. Moreover, dry food lasts for a longer time and is cheaper as compared to wet cat food. According to some experts, dry food is also better for a cat’s dental health. Wet food can lead to plaque buildup which is something that you do not have to worry about if you feed your cat dry food.

Wet food is an ideal choice for your feline friend during diarrhea. Since the cat is passing a watery stool, there is a shortage of water inside the body. Wet cat food can make up for this shortage ensuring that your cat is not dehydrated.

Similarly, if your cat has kidney disease, you should go for wet food as it is the better choice. However, wet food does not have a long shelf life. Once you open up the can, it is hard to store the leftovers. Also, wet cat food is more expensive. It is up to you to choose the best for your wet. During an episode of diarrhea, most vets would suggest you feed wet cat food to your cat. If your cat does not like wet food, you can opt for dry food. But you must serve this food with water so that the moisture levels can be maintained in your cat’s body.


Some parents make the mistake of feeding their feline kids a certain food without checking if it is age-appropriate or not. Yes, this is an issue and you need to be aware of it. Kitties need more protein in their diet so that they can grow and have more lean muscle mass. On the other hand, oldies need a low-calorie diet.

This will prevent them from getting obese or falling prey to diseases that come with old age. If you are a bit confused about this part, you can always call your vet and get advice on this.

Vitamin-Rich Foods

When nursing a cat suffering from diarrhea, it is imperative to feed them cat food that is rich in vitamins. Cats need vitamins for strengthening the immune system. If your cat’s immune system is stronger, it would not fall sick so often. Opt for cat foods that have Vitamin A, Vitamin B, and Vitamin E.


Since your cat cannot talk to you, you would have to experiment with a few cat food options before you find the most palatable choice for your pet. Cats are carnivorous by nature so it is understandable that they would be inclined towards chicken, duck, or fish.

You have to find out, through trial and error, whether your cat likes to eat fish or chicken. Once you have figured that out, you will be able to choose the best food for your friend.


You would not be very happy to know that most cat foods are not as hypoallergenic as you would like them to be. Your cat, especially when sick, needs foods that are free of allergens. If you accidentally feed your cat a hyper-allergenic diet, it would flare up diarrhea. If you have had your cat for a few months or a year, you would know about their allergies. If you are tending for a sick kitty and you are not aware of any allergies, there are a few allergens that you should try to avoid:

  1. Soy
  2. Dairy products
  3. Grain
  4. Gluten
  5. Corn

Better be safe than sorry, right? Keep in mind that allergens would only make diarrhea worse. This is why it is best to do your research well before time than regret it later on. In short, you are the best judge of what to feed your cat. Do not simply buy something because it is what your neighbor’s cat eats or it has higher reviews. The cat food you choose for your pet should be the best for your particular cat. Therefore, you would have to do your research and spend some time learning your cat’s body and taste to find the best cat food.
