Bottom Line

This may not be the best for sensitive pets, but we recommend this supplement as an appetite stimulant.

Pet owners with sick or sensitive cats should consider this formula that is praised for providing proven results in most cases.

Pros

A gentle formula that is a good choice for cats with sensitive digestive systems. Garners praise for easing diarrhea. Contains natural ingredients and no fillers. Very few issues getting cats to eat it.

Bottom Line

Many cats respond better to dog probiotics, so owners can use this product for either type of pet. We recommend mixing powder with fish or coconut oil to disguise flavor.

Pros

Effective against gas and bloating. Safe for both cats and dogs. Each capsule contains 10 billion beneficial bacteria – more than many other brands.

Cons

Can trigger diarrhea in some pets. Reports of capsules hardening over time. Not tasteless as claimed.

Cats sometimes suffer from digestive ailments but may exhibit their symptoms in different ways than we’re used to. Probiotics can help our feline-friends process food better and benefit from improved overall health as well. Most products are made in dry or liquid formulas, making it easy for your cat to consume on a regular basis. Owners benefit as well, via fewer vet visits, as probiotics are known to help control weight and provide cats with the healthy bacteria that’s missing from generic food brands. You’ll be impressed with most brand’s ingredient lists that include organic, gluten free options. More importantly, you can expect an improvement in your cat’s overall health, with a safe and sustainable probiotic additive.
