Got Questions? Here's What Cat Owners Ask Most
What benefits can I expect to see in my cat?
Most cat owners notice improvements within the first 1-3 months of daily use. Common benefits include:
Improved appetite — Cats often start eating more consistently, even those who've become picky or lost interest in food.
More energy — Less lethargy, more willingness to play, and a return to normal daily activity.
Normalized drinking habits — Less excessive thirst and more balanced water intake.
Better digestion — Fewer stomach issues, more regular bowel movements, and less vomiting.
Healthier coat — Shinier, softer fur as nutrient absorption improves.
Improved comfort — A more relaxed, content cat overall.
Results vary depending on your cat's age and current kidney health. Some owners also report improved bloodwork results at vet checkups after consistent use.
Are your cat supplements easy to use?
Yes, it takes less than 30 seconds a day.
Simply add 2 scoops to your cat's food. and mix it in. That's it.
The powder blends quickly into wet or dry food with no grit or clumps. It has a natural fish flavour which even picky eaters like.
No pills to force down. No syringes. No fighting at mealtime.
Do I have to sign up for a subscription?
No, you don't have to, but we recommend it. We now offer a subscription option in addition to one-time purchases.
We introduced subscriptions because consistency is one of the most important parts of building an effective daily routine for gut support. Probiotics work best when used continuously over time, and subscriptions help make sure your cat never misses a day.
You can still choose:
- One-time purchase — no recurring charges or commitments
- Subscribe & save — automatic deliveries on your preferred schedule
The subscription is fully flexible, so you can choose the delivery frequency that works best depending on how many cats you're giving it to and how quickly you go through each jar. You can also pause, change, or cancel anytime.
What are other cat owners saying?
Cat owners are seeing real results—and sharing them:
"Her bloodwork actually improved." — Linda M. Noticed better energy, healthier coat, and improved kidney values after two months of daily use.
"Stopped the vomiting and lethargy." — James K. His cat's digestion improved within weeks, with more energy and consistent appetite.
"Prevention before it's too late." — Rachel T. Started using it proactively after losing a previous cat to kidney failure. Peace of mind knowing she's supporting her cat's kidneys early.
The most common feedback we hear: improved appetite, more energy, and cats that actually eat it without a fight.
Is this formula science-backed?
Yes. Every ingredient is selected based on published research, not trends.
The gut-kidney connection is real. Studies show that harmful compounds produced in the gut pass into the bloodstream, forcing the kidneys to work harder over time. Targeted probiotics help break down these compounds before they reach the kidneys -- reducing the burden on an already stressed system.
Our 6-strain probiotic blend delivers 500 Million CFU of strains studied for their role in gut balance, toxin metabolism, and immune support.
Prebiotic inulin (from artichoke) feeds and sustains beneficial bacteria so they actually colonize -- not just pass through.
Pancreatin Fungal 4X enzymes support complete nutrient breakdown and absorption, reducing digestive stress on your cat's system.
Pumpkin powder and marshmallow root add a soothing layer of gut support, helping maintain a calm, healthy digestive environment.
This is not a generic blend. It is a targeted formula built to support kidney health from the inside out.
Do you offer free shipping?
Yes, on orders over $74.95, shipping is completely free.
Most customers qualify by stocking up with 2 jars, which also ensures you don't run out mid-routine.
Orders under $74.95 ship at a flat rate calculated at checkout.
How does the 60-day money-back guarantee work?
Simple. If you're not happy, you get your money back.
Try it for up to 60 days. If you don't see a difference in your cat, or you're not satisfied for any reason, just reach out to our support team.
No hoops to jump through. No awkward questions. We'll refund your purchase.
We offer this because we're confident in the formula. Most customers see real results. But if it's not the right fit for your cat, you shouldn't be stuck paying for it.
