Top Pick
This probiotic soft chew can be a useful add-on for cats who could use a little extra digestive support or are prone to mild tummy upsets. It combines several probiotic strains with a prebiotic fiber to help nourish beneficial gut bacteria. Because it’s a supplement, it should be fed alongside a complete and balanced cat food rather than as the main diet.

Strengths
- Provides multiple probiotic strains along with one billion CFU to help support a healthy gut microbiome.
- Includes fructooligosaccharides as a prebiotic, which helps feed and support beneficial bacteria in the intestines.
- Soft chew format with whitefish flavor can make it easier to give to picky cats compared with powders or capsules.
- Uses mixed tocopherols as a preservative, which helps maintain freshness without synthetic flavors or dyes.
Considerations
- This is not a complete and balanced diet, so it should only be used in addition to a regular cat food.
- Cats with fish allergies should avoid this product since it contains whitefish as a flavoring ingredient.
- Brewers yeast is generally safe, but very yeast-sensitive cats may not tolerate it as well.

Top 5 Ingredients Explained
01
FOS
Fructooligosaccharides (FOS) are non-digestible, soluble prebiotic fibers commonly added to pet foods and supplements to feed beneficial gut bacteria and support intestinal health. In dogs and cats they can help improve digestion, stool quality and immune support, but excessive amounts may cause gas or loose stools in sensitive animals so levels should be balanced and introduced gradually.
02
Brewer's Yeast
Brewer's yeast (deactivated Saccharomyces cerevisiae) is commonly used in dog and cat foods as a flavor enhancer and supplemental source of protein, B‑complex vitamins, trace minerals and immunomodulating components such as beta‑glucans. It can support skin, coat and general nutritional status, but may cause gastrointestinal upset or allergic reactions in yeast‑sensitive pets, is not a live probiotic, and should be used cautiously in animals prone to purine‑related issues or those receiving antifungal medications.
03
Vegetable Glycerin
Vegetable glycerin is a plant-derived humectant and sweet-tasting solvent commonly used in pet foods and treats to retain moisture, improve texture, dissolve flavorings or vitamins, and enhance palatability. It provides usable calories, is generally regarded as safe for dogs and cats in typical amounts, but excessive intake can cause digestive upset and may be a consideration for diabetic pets or those needing calorie-restricted diets.
04
FOS
Fructooligosaccharides (FOS) are non-digestible, soluble prebiotic fibers commonly added to pet foods and supplements to feed beneficial gut bacteria and support intestinal health. In dogs and cats they can help improve digestion, stool quality and immune support, but excessive amounts may cause gas or loose stools in sensitive animals so levels should be balanced and introduced gradually.
05
Whitefish
Whitefish (such as pollock, cod, or haddock) is commonly used in pet foods as a lean animal protein source that provides high‑quality essential amino acids, good digestibility, and some omega‑3 fatty acids to support skin, coat and muscle maintenance. While generally palatable and useful for weight‑managed formulas, pet parents should be aware of potential fish allergies and the importance of responsible sourcing and processing to minimize contaminants; cats also require adequate dietary taurine, so whitefish should be part of a complete, balanced diet.
