Cat Probiotics

In addition to helping cats who are already experiencing issues, probiotics can also be used to maintain good intestinal health and prevent problems from popping up. If you're interested in finding the best probiotic for your cat, read through our reviews below. We've reviewed five of the best options on the market to help you make a decision about which probiotic will be best for your kitty.

Top 5: Cat Probiotics Review

Proviable DC is a probiotic that is specially formulated for use with dogs and cats. It has seven strains of bacteria that are beneficial to the digestive systems in dogs and cats. Each of the seven strains has different properties, giving this option a higher chance of likelihood of colonization than if you were to use a single strain product.

Use of this option can support the intestinal health of your cat. If your cat is displaying signs of intestinal imbalance, such as a decreased appetite, vomiting, or diarrhea, adding this probiotic to their daily routine could help you see an improvement.

This product is also formulated to contain prebiotics. Prebiotics function as a source of food for probiotic strands to help them grow and work against harmful bacteria in the intestines.

Buying Guide

Purchasing a probiotic for your cat can make a big difference if they are experiencing digestive issues like vomiting, diarrhea, constipation, or a decrease in appetite. Because each probiotic you'll come across will differ slightly from other options, you'll want to take a little time to compare the different features of each option and think about what you're looking for in the product you select.

First, look for an option that includes more than one probiotic strand. Choosing an option with multiple strands will increase the chances that the probiotic will be beneficial for your cat. Selecting a product that has live strands will also lead to a greater chance of benefits for your cat.

Research has shown that Bifidobacterium Bifidum and Enterococcus are two probiotic strands that are most effective for cats. Bifidobacterium Bifidum can aid in the digestive process with cats and Enterococcus will help ensure that your cat's colon functions properly and is able to produce feces that is not too soft or too hard.

Next, you will want to pay attention to the CFU count in each of the options you're looking at. The CFU counts tells you the number of live microorganisms that are found in one serving of the probiotic. Finding a product with a CFU count in the billions can be most beneficial for your cat.

Another thing to consider is how you'll need to give your cat their daily serving of probiotics. Some options come in a pill or capsule form, some are powders you can sprinkle over a cat's food, and other options are treats. Think about your cat's preferences and choose an option that you think they'll take without trouble.

Finally, consider the cost and number of servings you'll receive with each option. Look for an economical product that still meets the other criteria we listed above. Price shouldn't be the only factor you use to make a decision, but it may be helpful when you're trying to decide between two otherwise similar options.

Best Cat Probiotic

After compiling our reviews above and comparing the different product options, we have concluded that the Proviable DC for Cats and Dogs is our top pick. If your cat is having digestive issues or you are looking to help keep their digestive tract healthy, this is a good option to consider.

Unlike many other probiotics than only have one strain of bacteria, this option includes more than seven different strains with billions of microorganisms in each dose. Choosing a product with multiple bacteria strains will increase the chances that it will keep your cat's digestive system healthy.

Prebiotics are also found in this option. The prebiotics work to help the probiotic strands grow, making them more effective with tackling harmful bacteria in your cat's intestines.

You'll receive a package of 80 capsules when you purchase this option. You'll only need to give your cat one capsule each day to give them their daily dose of probiotics. If your cat does not take pills well, you can also break open the capsule and pour the contents over your cat's food.

Frequently Asked Questions

What are probiotics for cats?

Probiotics are a supplement you can give to cats to aid in digestion. They are full of healthy bacteria that will help keep their digestive tract balanced.

What are the benefits of giving a cat probiotics?

There are many different benefits that are associated with giving your cat probiotics. They can help address digestive issues such as vomiting, diarrhea, or decreases in appetite. Taking a probiotic can also help you avoid these issues altogether and prevent your cat from developing them. Probiotics can also help a cat's immune system. Their immune system is linked to their digestive tract, so when they suffer from digestive issues, it could lead to problems with their immune system.

Can I give my cat a probiotic made for humans?

There haven't been enough studies done to determine if it is dangerous to give cats human probiotics. However, veterinarians recommend giving your cat a probiotic specifically designed for cats since they will be more effective. Cats' digestive systems are different from humans'. They have different microflora in their small and large intestines, so selecting a probiotic designed for cats will give them the greatest benefits.

What are some different forms that cat probiotics come in?

Cat probiotics come in a variety of different forms and packages. Many of the supplements are flavored to encourage cats to eat them, which takes some of the stress out of administering a dose.

You can find cat probiotics on the market in forms including:

  • Powder to be sprinkled in water or food
  • Pills to be administered by hand
  • Liquids that can be mixed with cat food or served separately
  • Treats for stubborn cats who don't want traditionally packaged supplements
  • Gel to be administered directly into the mouth

There are also probiotics that are formulated for different digestive issues. Some have certain digestive enzymes that help to soothe nausea and stomach cramps. Others are designed for use by young kittens. Still others are designed for cats with intestinal issues like inflammatory bowel disease.

The best one for your cat will really just depend on whether you want to give your cat a flavorful supplement or mix something flavorless into their food. It also depends on which type of supplement you'd find the most painless to administer.

How long does it take for probiotics to work in cats?

The exact time that the probiotics take will vary. It depends on your cat's digestive system, the form that the supplement was in, whether your cat ingested the entire dose, and what the chemical formula of the probiotic is.

You can expect to need to wait a little while to see the full effects. Most probiotics begin to show results within the first couple days after your cat starts regularly taking them. But more significant effects tend to take up to a few weeks to become apparent.

Can probiotics make a cat sick?

Right now, there hasn't been a lot of research done into the effects of human probiotic supplements on cats. Because human supplements are formulated for a human digestive tract rather than feline, they're unlikely to work as well. It's also possible that they could be harmful to your cat's digestion.

But there's very little to no evidence indicating that cat probiotics can cause a cat to become sick. If cats do become ill, the cause tends to be contamination due to poor processing. This is why it's important to buy supplements from a reputable brand.

The probiotics themselves won't hurt a cat's digestive tract, though. If your cat is already having perfect digestive health, the probiotics might not do much, but they also haven't been shown to cause harm.

What is the difference between cat and dog probiotics?

Cat and dog probiotics are formulated differently because the digestive systems of these animals are extremely different. Cats have shorter small intestines than dogs, so their food is digested more quickly.

Other parts of a cat's digestive system are also significantly smaller than a dog's. One example is the cecum, which is the pouch that connects the large and small intestines. In addition, dogs and cats have different compositions to the inner linings of their stomachs.

A cat is a true carnivore. That means that it's evolved to get all of its nutrients from meat. Dogs, on the other hand, are omnivores. While cats eat diets almost exclusively made up of fats and proteins, dogs eat a mix of protein, fruits, vegetables, and meats.

You can see this difference just by looking at the mouths of a cat and a dog. A dog's mouth has molars that are made to chop up plants. Cats don't have teeth like this because they aren't built to digest plant matter.

Because of how cats differ from dogs in their physiology and their diet, veterinarians have found that probiotics are more effective for cats than dogs.

How can I most easily give my cat a probiotic dose?

This will vary depending on the supplement. Most supplements will come with instructions for how to administer the dosage.

Many cat owners are familiar with the stressful experience of trying to force a cat to take antibiotics or pills. Though you can get probiotics in pill form, you can also purchase them in much more easily-administered ways.

Certain odorless and tasteless powders can be stirred into a cat's water or food without them being aware of the change. You can also purchase flavored probiotics in liquid or solid form and offer them to your cat as a treat.

Sometimes you will have pill capsules, and your cat might be unwilling to swallow them. If that's the case, you may be able to sprinkle the contents of the capsule onto the cat's food. It also sometimes helps to hide the capsule inside a cat treat so the cat eats it without realizing.

When should I give my cat a probiotic dose?

Generally, probiotics are recommended when a cat has been having intestinal issues. Some veterinarians may prescribe probiotic supplements as a treatment for consistent diarrhea. There are other practitioners who believe that probiotics should be incorporated into any cat's diet, regardless of whether they have digestive issues.

The theory is that by giving cats probiotic supplements, their digestive systems will be better regulated, which will prevent digestive problems from forming in the future. It's a preventative measure that can be helpful, provided your cat doesn't mind taking the supplement.

Another time when probiotics may be used is when your cat is on an antibiotics course. Just like in humans, antibiotics for cats tend to destroy the microbial flora in the gut. This makes digesting food much more difficult. When a cat has been on antibiotics, you can help replenish their digestive system by giving them daily probiotic supplements.

Some pet parents might wait until their cat has been on the antibiotics for a few days. Some might decide to give their cat probiotics and antibiotics simultaneously. After the course of antibiotics is done, it's helpful to keep giving your cat probiotics for several weeks afterward.

Are there any risks in giving cats probiotics?

As mentioned, it's extremely rare for cats to experience any ill effects from taking probiotics. But experts in the industry have talked about how important it is to be mindful of the brands you buy. Both human and pet supplements are very loosely regulated, and they don't have nearly the same standards as FDA-approved medications.

Many people don't realize that the FDA doesn't have any jurisdiction over supplements. But it's true. There is no government entity that regulates or inspects nutritional supplements. In addition, companies are not required to probe that the information on their product label is true.

Companies are required to respond to official complaints against them. But there's no real testing or oversight required before their products hit the market.

There is slightly more regulation of human supplements than animal ones. A veterinary organization has been formed to offer oversight of the supplement industry. This group, the National Animal Supplement Council or NASC, gives their label and certification to products that they've inspected and approved.

If you're looking for different probiotics, it can be helpful to look for products with the NASC label. These products have been proven to offer true information about effects, ingredients, and dosages on their labels. Supplements from companies that also create human supplements tend to be better regulated, too.

Experts do emphasize that different things will work for different pets. Scientists are still learning about how the digestive tracts of animals are different from those of humans. Different probiotics may have different effects. If the first probiotic you try doesn't seem to be showing results after a few weeks, another formula might work better.

Why has my cat had diarrhea for weeks?

Diarrhea occurs when your cat's stools are loose or liquidy. It happens because fecal matter moves more quickly through the intestine but doesn't absorb as much water, as many electrolytes, or as many nutrients. Rather than being a disease by itself, diarrhea is instead a symptom of another illness.

Diarrhea can be caused by many different conditions. Sometimes your cat might not have any other symptoms, but sometimes they might show signs of more specific diseases. It's also possible that a cat might suffer dehydration or other side effects if they are subject to frequent diarrhea.

Most causes of diarrhea involve inflammation of at least one part of the digestive tract. Inflammation can be caused by a variety of things, including:

  • Intestinal worms
  • Coccidia
  • Viruses
  • Bacteria
  • Poisonous plants
  • Toxic chemicals

When the cause is unrelated to inflammation, it's most commonly related to an allergy or a food intolerance. If you notice that your cat is having diarrhea following a change in diet, their new food might be irritating their digestive system.

If your cat has been having diarrhea for weeks without any apparent cause, it's time to see the vet. It will be helpful if you write your pet's chronological and detailed medical history prior to arriving at the clinic. That way, your vet knows how to assess the problem.

Some things to include in your history are:

  • The date that you first noticed the problem
  • A detailed description of the symptoms
  • Whether any changes were made to your environment or your cat's diet
  • How the symptoms have progressed since you first noticed them
  • Changes in your cat's usual household routine
  • Changes in the frequency of your cat's bowel movements
  • The smell, consistency, and color of the feces

If your cat has exhibited any symptoms other than the diarrhea, such as weight loss or lethargy, it's vital that you mention these as well. You'll generally be asked to bring a fresh stool sample to the appointment. The vet will then do an exam and may order additional clinical tests.

When there hasn't been an in-depth workup to determine the exact cause of the diarrhea, your vet might ask you to treat without a specific approach. Typically, this will involve giving your cat light and easily-digested foods alongside copious water.

Final Verdict

We think the Proviable DC Probiotic is a great option for you to consider. We also highly recommend any of the other probiotics we reviewed. They can all help you manage your cat's intestinal health and help relieve digestive issues.

Take some time to read through our reviews again and decide on which product is right for you. Then, place your order so you'll be able to help your cat with their digestive issues right away.
