KidneyRX™ - Kidney Support for FIP Cats

KidneyRx: Because Your Cat's Kidneys Need Protection During FIP Treatment

FIP is a disease that attacks on multiple fronts. While the virus itself drives systemic inflammation throughout the body, the kidneys quietly bear a significant share of the burden — filtering the byproducts of infection, processing weeks of antiviral medication, and managing the electrolyte disruptions that come with serious illness. For many cats, this sustained pressure on renal function goes unaddressed during treatment. KidneyRx changes that.

Formulated specifically to support feline kidney health during and after illness, KidneyRx is strongly recommended as part of every FIP treatment plan — because protecting your cat's kidneys from the start gives them a stronger foundation to recover on.

What KidneyRx Does for Your Cat

Every ingredient in KidneyRx has a specific job to do:

• Calcium Carbonate acts as a phosphate binder, helping to keep phosphate levels in check — one of the most important things you can do to protect kidney health during prolonged illness or medication use.
• Magnesium Carbonate helps maintain electrolyte balance, which is frequently disrupted in cats under the physiological stress of FIP treatment.
• L-Carnitine supports healthy fat metabolism and energy production, while helping to reduce the accumulation of toxic metabolites that the kidneys would otherwise have to work harder to clear.
• Chitosan binds to toxins within the digestive tract before they enter circulation, directly reducing the filtration load on the kidneys — with studies showing measurable reductions in creatinine levels with consistent use.
• Vitamin D (50 IU) addresses a critical gap in sick cats: because compromised kidneys cannot efficiently convert vitamin D to its active form, supplementation helps maintain healthy calcium and phosphorus regulation and protects bone integrity throughout recovery.
• Omega-3 Fatty Acids (EPA & DHA) deliver targeted anti-inflammatory support at the renal level, helping to reduce inflammation-driven damage to kidney tissue during active disease.
• Cranberry Extract supports urinary tract health and helps maintain the environment in which the kidneys function — an often-overlooked but important part of overall renal care.

What You Can Expect to See

Cats receiving KidneyRx as part of their FIP protocol tend to show:

• Better energy and activity levels as toxic metabolite burden is reduced and cellular energy production improves
• Improved hydration and urinary output as kidney function is actively supported rather than left to cope on its own
• More stable bloodwork over the course of treatment, particularly in creatinine and phosphate values
• Reduced risk of long-term kidney complications following recovery — giving your cat the best possible quality of life after FIP

Our Recommendation

Every cat going through FIP treatment deserves full-body support — not just antiviral therapy alone. The kidneys work tirelessly throughout the entire treatment journey, and they deserve the same attention we give to the liver, the immune system, and the virus itself.

KidneyRx is safe, well-tolerated, and designed to work seamlessly alongside your cat's existing FIP protocol. We strongly recommend it for every cat in treatment, from the very first dose to full recovery and beyond.

Because beating FIP isn't just about eliminating the virus. It's about bringing your cat back whole.
