Probiotics are beneficial bacteria that support digestive health and overall wellbeing in cats. These supplements help maintain a healthy balance of gut bacteria, which can improve digestion, support the immune system, and help manage digestive issues like diarrhea or constipation. Probiotics can be especially beneficial after antibiotic treatment, during stress, or for cats with chronic digestive problems.

What to Look For in Cat Probiotics
When choosing probiotics for your cat, consider these important factors:
CFU Count
CFU (Colony Forming Units) indicates the number of live bacteria in the product. Look for products with at least 1 billion CFU per serving, though higher counts (5-10 billion) may be more effective for cats with significant digestive issues.
Strain Diversity
Products with multiple bacterial strains provide broader benefits than single-strain products. Look for probiotics containing several beneficial strains like Lactobacillus and Bifidobacterium species.
Form
Probiotics come in powders, capsules, pastes, and treats. Choose the form that's easiest to administer to your cat. Powders can be mixed with food, while treats may be more palatable.
Survivability
The probiotics must survive stomach acid to reach the intestines where they're needed. Look for products with enteric coating or strains that are naturally acid-resistant.
