Probiotics for cats help maintain healthy gut flora and can support your pet’s overall immune system, in addition to helping with a range of gastrointestinal issues. There are various formulas and options out there, so read on to learn which probiotics are the best fit for your cat’s needs!

The benefits of probiotics for humans are many, but what about cats? Can our pets benefit from good bacteria in their digestive tract? Probiotics for cats are a great way to introduce beneficial bacteria to regulate their gastrointestinal and overall health. Microorganisms in the gut help with various issues, from minor disturbances such as upset stomach to more complex problems such as weaker immune systems. Unfortunately, most cats don’t have a diet and lifestyle that leads to thriving gut flora.

In the wild, our pet’s ancestors would get everything they need from their prey, including good (and bad) bacteria. That’s not always the case with commercial pet food, so there’s sometimes a need to introduce cat probiotics separately to regain balance and heal their digestive system. There are various types of probiotics for cats out there, from different formulas to different delivery methods- we’ve handpicked the best probiotics for cats to make your choice easier.

4. Best for Diarrhea: VetOne Advita Powder Probiotic Nutritional Supplement for Cats

Bouts of diarrhea are not just unpleasant but can be dangerous for your pet. Whether the diarrhea is acute or chronic, it can lead to dehydration, poor absorption of nutrients, and further health issues. VetOne Advita Powder Probiotic Nutritional Supplement for Cats helps your pet get normal stool consistency once again, as well as support their digestive health in general. This is achieved thanks to 4 live, active cultures and prebiotic inulin, including a minimum of 200 million total colony-forming microorganisms in each packet.

Micro-encapsulated for better stability, this cat probiotic supplement also contains vitamins A, C, and E to give your cat’s immune system a boost, as well.

5. Best for Constipation: Vetrinex Labs Cat and Dog Probiotics with Digestive Enzymes

Chronic constipation is no fun- often affecting senior cats or those suffering from certain medical issues, constipation can be painful, frustrating, and downright dangerous if not treated on time. With the main goal of restoring balance back to your cat’s GI tract, Vetrinex Labs Cat and Dog Probiotics with Digestive Enzymes combines the two most powerful digestion aids into one formula. Digestive enzymes support nutrient absorption and improve digestion, while a potent blend of 7 carefully selected species of beneficial bacteria will quickly restore gut balance and help normalize your pet’s stool and regularity. Potent and highly efficient, this powdered probiotic contains 3 billion CFUs per scoop- and it’s easy to sneak into food, too.

6. Best for Allergies: Strawfield Pets Cat Probiotics

Cats with allergies, especially those that have food sensitivities, often have issues with gut flora. Some research suggests that a thriving, diverse gut microbiome could mean fewer allergy symptoms, and the best way to populate your cat’s gut with beneficial bacteria is through probiotics. Strawfield Pets Cat Probiotics have a unique formula that combines multiple beneficial ingredients that help the immune system, digestive health, and promote healthier skin and coat- all of which are issues that allergic cats struggle with.

With 5 strains of bacteria and 2 billion CFUs, this supplement is more than able to soothe your cat’s upset stomach and improve their gastrointestinal health, whereas wild-caught Alaskan salmon oil adds a boost of essential fatty acids needed for reduced itching and skin dryness. To top it all off, this probiotic supplement is also fortified with L-lysine, an amino acid essential to cats, which supports their overall health and improves their immune system. While all of these ingredients were enough to impress us, our felines might not be as enthusiastic about these chews- which is why there’s catnip in the formula to make this supplement irresistible to any feline who needs them.

7. Best for Kittens: PetAg Bene-Bac Plus Pet Gel

Kittens are very fragile, particularly bottle-fed orphans. For a kitten, diarrhea or gastrointestinal upset could even be fatal, so it’s crucial to react quickly and make sure that they pass stool normally. PetAg Bene-Bac Plus Pet Gel is easy to dose and administer and can even be given to kittens as young as newborns. You can administer it directly or smudge over your pet’s paw and they will lick them on their own. The probiotic gel contains a concentrated live culture of seven fat encapsulated microorganisms found in the intestinal tract of small mammals that produces 20 million CFU of viable bacteria per gram. As a result, this supplement will quickly and efficiently stop diarrhea in kittens and normalize their digestion. A lifesaver- literally!

8. Best for Hairball Relief: Get Naked Furball Relief Soft Treats for Cats

Cats are avid groomers, but that comes with one major side-effect: hairballs. While, usually, it doesn’t take much for the hairballs to pass normally with the stool, sometimes the hair builds up in the gastrointestinal tract which causes issues such as coughing, vomiting, or even constipation. Get Naked Furball Relief Soft Treats for Cats are formulated to prevent this from happening by utilizing natural dietary fiber, flaxseed, prebiotics, and probiotics in their treat formula. The patented beneficial bacteria strain Gained BC30 will support healthy digestion and stool regularity, and with the addition of natural oils, it will be easier for your cat to pass hair when they go potty. Also, it doesn’t hurt that this supplement comes in the form of a chicken-flavored treat that felines are bound to go bananas for!

9. Best for Anal Glands: Glandex Cat Anal Gland Sac Fiber Supplement

While most cats can express their anal glands without assistance, sometimes, their dietary habits can make matters more complicated and cause inflammation or even infection. Naturally, in most cases, this can be remedied when gut health improves, and probiotics are a great way to do just that. Glandex Cat Anal Gland Sac Fiber Supplement is formulated specifically to target issues that precede anal gland problems. The supplement includes pumpkin seed, omega fatty acids, probiotics, and digestive enzymes blended together for a potent effect. Its formula is optimized to cause bulkier and firmer stools that will naturally express the glands on the way out- it ain’t pretty but it gets the job done.

Benefits of Probiotics for Cats

A healthy gut is important not just for digestion, but for your pet’s overall health. When there aren’t enough good bacteria in your cat’s digestive system, it can trigger a host of issues ranging from vomiting, gassiness, and diarrhea, to skin and coat issues and a weakened immune system. This is why many pet owners decide on supplementing probiotics and prebiotics in their cat’s diet. Most cat diets based on regular commercial pet food don’t offer enough fiber and live probiotics your cat’s body could utilize, so unless you are feeding a specific diet for digestive issues, you would have to introduce probiotics separately. Here are some of the main benefits of probiotics for cats:

  • Improvement in appetite- often much needed for seniors and kittens
  • Stool stabilization- helps with constipation and stops diarrhea
  • Re-balances gut flora after a course of antibiotics
  • Can help support an optimal immune system
  • Can improve quality of life for cats with IBD, infections, or food sensitivities
  • Easier passing of hairballs
  • Soothes upset digestive tract in stressful situations

Of course, as is the case with any supplements or changes in diet, it’s best to consult with your veterinarian first. They know your pet’s medical history and can advise you what works best for their unique needs and save you a lot of trouble in the long run. This is particularly important if your pet has chronic digestive issues, as it’s crucial to eliminate any serious underlying issues that could be causing the symptoms- those that would require extensive therapy rather than probiotics.
