Are Probiotics Missing from Your CKD Cat’s Care Routine?

Have you ever thought, “Aren’t probiotics just for digestion?”

If your cat is living with kidney disease, probiotics can mean much more.

This connection is known as the Gut–Kidney Axis, a key pathway that links the intestines to the kidneys.

When gut health declines, the kidneys suffer.

In cats, gut-derived toxins can be reabsorbed into the bloodstream and passed to the kidneys.
This forces the kidneys to filter out extra toxins, placing added strain on already weakened organs.

That’s why supporting the gut is essential for protecting kidney function.

Probiotics do more than you think:

  • Reduce toxin production in the gut
  • Protect the intestinal lining
  • Maintain healthy microbial balance

Together, these benefits help reduce the burden on the kidneys.

Greycoat family cats like Lulu, Milo and TT have consistently maintained stable kidney values over time with routines that include the Probiotics Protocol.

Milo, now 14 years old, has regained his energy and appetite since adding the Probiotics Protocol to his daily routine.

So what kind of probiotics are right for cats?

Cats have shorter, more sensitive digestive tracts than humans.
This means high-dose human probiotics can overwhelm their systems and may even irritate the gut lining.

  • CFU: 1 to 3 billion CFU per day
  • Form: Capsules are generally the most effective form for cats.
  • Avoid: Treat-style probiotics, which may lose potency during heat-based manufacturing
  • Best time to give: On an empty stomach in the morning, when stomach acid is lowest 

Why Greycoat’s Probiotics Protocol Works for Cats
