    First Ingredient: Deboned chicken
    Fiber: 3,5%
    Size: 5 pounds

    Blue Buffalo Wilderness Kitten Chicken Recipe Grain-Free Dry Cat Food is another great high fiber food that also provides your pet with the most protein on this list at 40%. LifeSource Bits provide your cat with vitamin and mineral fortification that will help boost your pet’s immune system. Real fruits and vegetables, like pumpkin, blueberries, cranberries, sweet potatoes, and more, also provide important nutrients. Flaxseed, along with fish oil, is a great source of omega fats.

    The downside to Blue Buffalo Wilderness Kitten food is that some kittens don’t like it, similar to many other healthy foods. We also felt that the kibble was a little too large for our small kittens.

    • Omega fats
    Cons
    • Large kibble

    Fiber: 3,5%

Fresh fruits and vegetables like blueberries and cranberries also provide plenty of important nutrients your kitten requires to stay healthy. LifeSource Bits provide antioxidants, and fish oil provides omega fats.

    The downside we experienced while using Blue Buffalo Healthy Growth was that our cats sorted through it to pick out the LifeSource Bits and left the rest. We also had a problem with the packaging, and more than one bag had a hole that resulted in food on our floor and made it challenging to keep fresh.

    Pros
    • Whole grains
    • Fresh fruit and vegetables
    • Omega fats
    • LifeSource Bits
    Cons
    • Poor packaging

    Buyer’s Guide: Selecting The Best Kitten Food for Diarrhea

    Keep these aspects in mind when you’re narrowing in on food for your sick kitty.

    Fiber

    When choosing a kitten food for diarrhea, one of the first things we recommend looking for is a brand high in fiber. Fiber can help regulate the water in the intestines preventing both diarrhea and constipation from occurring. It’s also great for colon health because it allows the kitten to expel waste faster. We tried to list the fiber content of the brands on our list.

    Probiotics and Prebiotics

    Probiotics are the good bacteria in your kitten’s gut and supplementing them with commercial food will help them grow to develop a stronger digestive tract. A stronger digestive tract can also help boost the immune system, as some studies show that a stronger gut promotes a stronger defense against bacteria.

    Prebiotics are the food that probiotics eat. These nutrients can help the bacteria grow and multiply much faster than they normally would. In some cases, prebiotics can be as effective as probiotics but usually take a little longer before they become effective.

    Dry Food Versus Wet Food

    We recommend feeding your kitten dry kibble, especially if it suffers from frequent diarrhea. Wet food has too much moisture that frequently causes diarrhea, and there is a good chance you will notice a big change in your cat after switching to dry food. Dry kitten food will also help clean the teeth as your kitten chews by scraping away tartar. It may not seem important at this early stage of your pet’s life, but some experts suggest that more than half the cats over three in the United States have some form of dental disease, so it makes sense to start keeping the teeth clean immediately.

    What Causes Diarrhea?

    Several things can cause diarrhea, including poor health, so it is important to visit a vet if the problem doesn’t clear up In a few days after changing foods. In our experience, many people give their kittens wet food because they fear kibble is too hard to chew, but canned food is very rich and contains a lot of moisture which can cause a lot of cats to have loose stools, gas, and diarrhea. Inexperienced parents also like to give the kittens milk, but after your kitten switches to regular food, it becomes lactose intolerant, and dairy milk will easily cause diarrhea. Finally, many budget brands contain artificial dyes, preservatives, and other low-quality ingredients that can throw your kitten’s digestive tract off track. We recommend choosing your kitten food like human food by looking at the ingredients and avoiding brands with long lists of hard-to-pronounce items.
