How Catology Probiotic Serum Works
Using Catology is simple — add a few drops to your cat’s daily meal.
Once ingested, our clinically supported probiotic strain Bacillus Coagulans activates in the gut, helping restore a healthy microbiome and reducing inflammation. It works by forming a protective environment that supports smoother digestion and stronger immune function within just a few days.
For best results, use it consistently for 14 days.
Most cat owners notice improvements within 48–72 hours — reduced vomiting, firmer stools, better appetite, and calmer behavior.
Within 2–3 weeks, many report better hydration, steadier energy levels, healthier stool quality, and an overall boost in comfort and vitality.

Why Your Cat’s Gut Controls Their Overall Health
Your cat’s gut does far more than process food — it plays a central role in immunity, inflammation control, hydration, energy levels, appetite, and long-term organ function.
A healthy microbiome filters toxins, supports nutrient absorption, and helps keep digestion smooth and stable.
But many cats lack enough beneficial bacteria to maintain this balance. Age, stress, processed foods, and daily environmental factors weaken the microbiome, allowing toxins to recirculate instead of being eliminated.
When the gut becomes unbalanced, you may notice:
- Reduced appetite
- Diarrhea, vomiting, or loose stools
- Low energy or lethargy
- Increased thirst
- Weight changes
- Anxiety or overgrooming
Restoring gut balance is the foundation for improving digestion, comfort, behavior, immunity, and your cat’s overall daily well-being.
The Catology Method: A Probiotic That Actually Reaches the Gut
Up to 90% of traditional probiotics are destroyed by stomach acid, meaning they never reach the intestines — where real improvement begins.
Catology uses a clinically studied strain, Bacillus Coagulans, protected by a natural spore coating.
This allows the probiotic to survive stomach acidity, reach the gut alive, and begin restoring microbiome balance at the source.
Once activated in the intestines, Catology helps:
- Reduce diarrhea, vomiting, and digestive flare-ups
- Improve stool quality and regularity
- Enhance nutrient absorption for better vitality
- Calm stress-related behaviors via the gut–brain axis
- Strengthen immune health over time
Many cat owners report visible improvements in 48–72 hours, with deeper, longer-lasting benefits appearing after 2–3 weeks of consistent use.
