What Are Probiotics for Cats?

Probiotics are live microorganisms—often called “good bacteria”—that restore and maintain a healthy balance in the gut. For cats, probiotics are essential in regulating digestion, preventing diarrhea, supporting immunity, and ensuring nutrient absorption. By boosting the microbiome, probiotics directly improve feline digestive health and help manage common problems like chronic loose stools and stress-related diarrhea.

Why Cats Get Diarrhea

Cats may suffer from diarrhea for many reasons:

• Dietary Changes: Switching to new cat food too quickly.
• Food Sensitivities: Allergies to dairy, grains, or certain proteins.
• Infections: Viral, bacterial, or parasitic infections.
• Antibiotic Treatments: Antibiotics kill both harmful and beneficial bacteria.
• Stress and Anxiety: Cats are sensitive, and stress can upset digestion.
• Chronic Conditions: Issues like IBD (inflammatory bowel disease) or pancreatitis.
• Toxins or Spoiled Food: Accidental ingestion of harmful substances.

Adding probiotics for cats with diarrhea can help address many of these root causes naturally.

Benefits of Probiotics for Cats with Diarrhea

• Strengthens Immunity: 70% of a cat’s immune system is in the gut.

• Supports Long-Term Health: A healthy gut promotes a shiny coat, strong immunity, and reduced hairballs.

• Enterococcus faecium – improves stool quality.
• Saccharomyces boulardii – stops antibiotic-related diarrhea.
