Is Your Cat Missing a Key Part of Kidney Care?

You might be doing everything right: prescription food, subcutaneous fluids, and AIM support. But your cat’s condition still isn’t improving. If gut health is left unmanaged, all those efforts may not be enough. Inflammation and a leaky gut can push harmful waste into the bloodstream, overwhelming the kidneys and undoing all your hard work to support your cat.

The Link Most Kidney Supplements Miss

The gut and kidneys are more connected than most cat owners realize.

When the gut lining becomes inflamed or compromised, harmful substances can leak into the bloodstream. This added waste puts more pressure on a cat’s already vulnerable kidneys, especially in those with kidney disease. This connection is part of what’s known as the Gut-Kidney Axis—a pathway that needs to be protected to give your cat the best chance at long-term stability.

That’s why Greycoat Research created Probiotics Protocol.

This targeted formula helps reduce kidney waste and rebalance the gut, giving your cat vital internal support for more consistent and reliable care. If you want to protect your cat’s kidneys, supporting gut health needs to be part of the plan.

What Makes Probiotics Protocol Different

  • Kidney-Specific Formula: Includes probiotic strains selected for their role in reducing kidney waste and inflammation
  • IBD Support: Targets inflammation to help manage symptoms like diarrhea, vomiting, and poor nutrient absorption
  • Clinically Informed: Shows trends of reduced BUN, creatinine, and gut-derived waste (GDUT) levels in stage 2–3 kidney disease cats
  • High Potency: 9 probiotic strains delivering a guaranteed 2 billion CFU per capsule
  • Neutral and Easy to Feed: Capsule has no added flavors or smells, making it easier for cats to accept

When What You’re Doing Isn’t Working

Greycoat Research recommends Probiotics Protocol to cat owners if their cats are experiencing any of the following:

  • Healthy cats to cats diagnosed with stage 1-3 kidney disease
  • Cats with frequent digestive issues such as vomiting, diarrhea, or poor stool quality
  • Cats with disrupted gut balance after antibiotic use
  • Cats needing additional gut health support as part of overall kidney care

Get your cat the kidney disease care they need for before it's too late!

The Most Proven Solution to Kidney Care for Cats

Greycoat Research has conducted over 1,000 consultations with cats in stage 2 and 3 kidney disease—and one method stood out. Cats that received a combination of AIM activation, uremic toxin reduction, and cellular protection showed the most stable values and clearest improvements over time.

The Kidney Support 3-Set is built around that strategy, combining three complementary supplements:

  • Dr. Toru Protocol: For AIM activation and kidney waste removal
  • Probiotics Protocol: For toxin reduction and IBD care
  • Intensive Protocol: For antioxidant support and cellular survival

When used together, these supplements target different aspects of kidney health and work more effectively than any single product alone.

Why IBD Matters for Cats with Kidney Disease

Inflammatory bowel disease (IBD) causes chronic inflammation in the digestive tract, which can interfere with nutrient absorption and lead to symptoms like vomiting, diarrhea, and weight loss. For cats already managing kidney disease, IBD can add further strain by introducing inflammatory substances into the bloodstream. Supporting gut health becomes even more essential when both conditions are present.

Easy to Give, Every Day

  • 1 capsule daily before meals, regardless of weight
  • It’s best to give the capsule before meals for optimal absorption.
  • You can offer the capsule whole or open it and mix the powder into wet food or a favorite treat.
  • Consistency is key—aim for daily use over at least 60 days for best results.

Key Ingredients and Their Roles

Probiotics Protocol contains 9 kidney-targeted probiotic strains selected for their unique roles in supporting gut and kidney health.

  • Toxin Reduction: Lactobacillus acidophilus, Streptococcus thermophilus, Bifidobacterium breve, Lactobacillus casei, Bifidobacterium lactis, Lactococcus lactis
  • IBD Care: Bifidobacterium longum, Lactobacillus plantarum, Lactobacillus rhamnosus

Together, these strains support a healthy gut environment, reduce the formation of kidney waste, and help manage IBD.

After my cat’s kidney levels went up I was worried about what to do, but I found out about Probiotics Protocl. Even though I started feeding it to my cat for kidney support, it ended up doing wonders for his poop, too! So it’s good for both kidney and gut health! I’ll make sure to keep giving it to my cat!

I read that giving cats probiotics regularly was good for them, so I made sure my cats got them from an early age. I trust Greycoat Research’s products so when they released their new probiotics I switched to that! I’m sure my cats guts will thank me later!
