Health Meter Cat Litter

Detecting a potential feline illness is now possible with Health Meter Cat Litter.

By: Leila Lotfi

The Early Detection System in Health Meter Cat Litter detects liver disease, kidney disease, stones and crystals.
Imagine being able to observe irregularities in your cat days before more obvious signs of illness appear. Nullodor USA’s Health Meter Cat Litter now gives owners the benefit of knowing that their cat’s health could be at risk.

Health Meter Cat Litter’s Early Detection System detects four common illnesses found in cats: bladder infection, liver disease, kidney disease and stones/crystals.

“There is no other cat litter that will detect the four most common cat health problems like we do,” says John York, president of Nullodor USA, LLC, based in Miramar Beach, Fla.

More than three years of research and development went into Health Meter Cat Litter, developed in France by Dr. Francois Mestrallet. His mission was to produce a cat litter that would provide superior liquid absorption and detect early symptoms of common feline diseases all while eliminating odor. Since its unveiling at Global Pet Expo in March 2006, Health Meter Cat Litter has become available in more than 900 Petsmart stores in the U.S. and is now sold in Australia and Canada.

Continued use of Health Meter Cat Litter allows owners to monitor their cat’s health and detect signs of a possible health problem. However, it should be used as an everyday cat litter and not just to detect health problems, says York. 

Unique color-coding crystals allow owners to observe irregularities in their cat. While there isn’t any specific color associated with one type of health problem, a pH greater than seven is usually blue, liver/kidney detection is often green and stones/crystals are red. Owners won’t see a distinct red, green or blue since multiple things can be in the cat’s urine at any given time. There’s a very dramatic color change in the litter when there’s any form of detection, says York.  “You can’t miss it!”

“We don’t want to play veterinarian,” he says. “If the color is anything different from what [the owner] normally sees, they should take their cat to the vet.”

I just found out that Petco has discontinued this product. Please advise where I can purchase this litter. I LOVE IT. It has truly helped save the life of both of my cats by detecting an issue. Please tell me where to purchase this product in Northern IL or Southern WI. Or better yet; can I have it direct shipped...
