Bottom Line

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

Pros

Effective and fast when combined with antibiotics. Flavor appeals to finicky eaters. Also addresses skin disorders.

Cons

Not ideal for cats on "limited ingredient" diets. Some post-meal vomiting reported. Better as an appetite stimulant.

Bottom Line

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.

Cons

On the higher end of the price range. Rare reports of cat owners not seeing a difference; but many more satisfied customers.

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.
