Cats Vitamins & Supplements: Frequently Asked Questions

What kind of probiotics are good for cats?

The best probiotics for cats contain strains specifically beneficial to feline gut health. Look for options with Enterococcus faecium, Lactobacillus acidophilus, or Bifidobacterium animalis. These strains help support digestion, manage diarrhea, and improve stool consistency. Choose a product made for cats—human probiotics aren’t the same. Bonus if it’s veterinarian-approved, third-party tested, and free from artificial additives. Powders and capsules mixed into food usually work best. Yes, even for picky eaters.

Is it okay to give cats probiotics every day?

Absolutely—daily probiotics can be beneficial for most cats. Regular use supports a balanced gut microbiome, improves digestion, and can even help with issues like hairballs or soft stools. But here’s the catch: not every cat needs them forever. Short-term use is fine for occasional tummy troubles. Long-term use? Talk with your vet first. Some cats might need a break or a different formulation depending on their health. Always start low and monitor how your cat responds.

What is the most effective form of probiotic?

Powder forms top the list when it comes to effectiveness—especially those you sprinkle onto food. They’re easy to dose, better absorbed, and less stressful than pills (cats aren’t great pill-takers, let’s be real). That said, chews and capsules are effective too, as long as they contain the right strains and enough CFUs (colony-forming units). Look for at least 1-5 billion CFUs per dose. And remember—probiotic effectiveness isn’t just about the form; storage and expiration matter too.

Is it okay to give my cat FortiFlora every day?

Yes, FortiFlora can be given daily, but there’s a “however.” It’s designed for short-term digestive issues, like stress-related diarrhea or post-antibiotic recovery. While many vets do recommend daily use in some cases, especially for older cats or those with chronic GI issues, it’s still best to use with veterinary guidance. Long-term, you’ll want to avoid it becoming a crutch “just because.” Also, it contains animal digest as a flavor enhancer—which some pet parents prefer to avoid.
