Diarrhea can be a serious issue for cats because it can quickly dehydrate them. Most cats don’t like to drink water which will make it hard to replenish the fluids lost. Dehydrated cats can suffer from excessive dander, and their diarrhea can quickly turn to constipation. While health problems and other issues can cause diarrhea, the food it eats is usually the main reason. If your cat suffers from frequent diarrhea and you would like to know which foods can help prevent it, you’ve come to the right place. We’re about to review several different brands to see how they cure and prevent diarrhea. We’ll give you the pros and cons of each one and tell you how our cat liked it. We’ve also included a short buyer’s guide to help you know what to look for if you continue to shop. Keep reading while we discuss ingredients, moisture, food type, and more to help you make an informed purchase.

Size: 11.5 Oz

First Ingredient: Chicken, Turkey or Beef

Smalls Human Grade Fresh Cat Food is our pick for the overall best cat food for a firm stool. Its gently cooked, all-natural recipes are unlikely to cause flatulence or loose stool. They contain human-grade ingredients including vegetables that provide important nutrients and a source of fiber. With chicken, turkey, or beef as single protein alternatives, there is an alternative option for cats with sensitivities. The pulled formulas also contain flaxseed, a source of fiber that helps to regulate gut motility and give consistency to stool.

We love Smalls as it provides species-appropriate complete and balanced nutrition to your cat, they offer different presentations in their fresh formulas to provide just the right texture for your cat. While having the food delivered right to your door on a regular basis is a great advantage, it requires economic planning, especially considering that this food is more expensive than commercially available kibble. The great health benefits on your cat’s digestive system, stool consistency, and overall health are worth the price tag and will save you on future vet bills, this is why Smalls is our best overall!

We liked using Halo Holistic. Most of our cats liked it, and it helped firm their stools. The only thing we didn’t like about this brand was that the kibble is quite small, leading to fast eating.

We liked Purina Pro Plan because it’s easy to find in most grocery stores, works well, and most of our cats seemed to like it. However, it’s not without problems. It contains soy ingredients which we usually try to avoid because it’s a filler that can lead to weight gain. It’s also high in calories at more than 500 per serving, so you will need to watch portion size carefully.

Pros

High in protein

Rice helps absorb moisture

Prebiotic fiber

Cons

High in calories

Hill’s Science Diet Adult Sensitive Stomach & Skin Chicken & Rice Recipe Dry Cat Food is the last brand on our list, but it still makes a great choice, especially if a vet prescribes it. It contains an easy-to-digest formula that won’t result in diarrhea or constipation and will help your pet maintain a firm stool. Another positive thing about using this food is that most of our cats like it.

Unfortunately, this veterinarian-prescribed food is extremely expensive and doesn’t contain the best ingredients. It’s lower in protein than the other brands we’ve looked at so far and higher in calories and more than 500 per cup. The idea is that you will feed your cat less, but in our experience, they forgot to explain that to the cat, and this food can quickly lead to weight gain if you’re not careful with portion control.

Buyer’s Guide: Selecting The Best Cat Food for Firm Stool

Avoid Trigger Ingredients

While health problems can often be why your cat suffers from diarrhea or constipation, food is often to blame. Avoid any foods that contain dairy products, including eggs, until you locate the source of the problem. Some brands contain ingredients like pumpkin that can be helpful to clear up constipation but might lead to diarrhea in a healthy pet. Your cat might also be sensitive to chemical preservatives or artificial food coloring, so make sure the brand you choose doesn’t contain them.

Limited Ingredient Foods

Some brands contain long lists of ingredients, and cats have sensitive digestive systems, so nearly anything can be causing problems. The best way to locate the source of your cat’s trouble let’s start by using limited ingredient foods. These brands only contain what’s necessary to provide your cat with a complete and balanced diet, so it will be easier to narrow down the list of problem ingredients.

Changing Foods

Owners often report that their cat experiences diarrhea, flatulence, and even vomiting when they change brands. In many cases, your pet will need a short time to adjust to the new recipe, but if it lasts more than a few days, we recommend trying a different brand as the new food might contain ingredients that cause your pet to have diarrhea or constipation. Take note of the ingredients in the two brands as they might give you a clue about problem foods your cat needs to avoid.

Giving your pet the highest quality nutrition is a top priority, so why not give them a food and water dish to match? We think the Hepper Nom Nom Bowl is too good not to share.

Made from food-safe stainless steel, you can ensure that your pet is consuming the best nutrition out of the finest bowls on the market. Click here to get yours.

At Pet Keen, we’ve admired Hepper for many years and decided to take a controlling ownership interest so that we could benefit from the outstanding designs of this cool cat company!

Wet Food vs Dry Food

Many people like to feed their cats wet food because of the higher moisture content. However, wet food is also very rich and high in fat, so it can easily lead to diarrhea and even vomiting, especially if your cat isn’t used to eating it. Wet food makes a nice treat, and it can be helpful if your cat is suffering from constipation or needs to take medicine, but dry food helps clean teeth, promotes a healthy weight, and doesn’t cause diarrhea as frequently.
