The ultimate cat litter

Check the health of your cat IN SECONDS.

Your cat can't tell that anything is wrong. CatCheck does; subtle color changes in the grit after a visit to the bowl let you see immediately how your four-legged friend is really doing.

All clear. Light yellow to olive green is considered a normal range. A stable color means your cat’s urine is within a healthy pH and hydration level.

Possible blood — call your vet. Red discoloration may indicate blood in the urine, which could signal an infection, injury, or kidney issue. Don’t wait get it checked.

Acidic — may indicate stress or kidney strain. Orange tones suggest low pH. This can be linked to metabolic acidosis, dietary factors, or early signs of renal imbalance.

Alkaline — may signal infection or crystals. Blue or greenish hues point to high pH levels. This could be a sign of a urinary tract infection or struvite crystal formation risk.

How to use health signal cat litter

Start Fresh

Begin with a clean litter box. Pour Health Signal to create a 5 cm layer covering the bottom. This ensures optimal odor control and provides a fresh start for your cat.

INITIAL COLOR CHECK

Within 1-2 hours after your cat uses the litter box, compare the color of the crystals to the providedguide. This initial check helps you start tracking potential health indicators.

ESTABLISH A BASELINE

Observe the color changes daily. After 5 days, identify the most common color within the normal range. This becomes your cat’s baseline health color.

DAILY Maintenance

Scoop out solid waste daily to keep the litter box clean. Regular maintenance ensures a healthy and pleasant environment for your cat.

Maintain Depth

Gently stir the litter every day and add more Health Signal as needed to maintain a consistent 5 cm depth. This keeps the litter effective and extends its usability.

MONTHLY REFRESH

Once a month, empty and clean the litter box completely. Refill it with a new bag of Health Signal for continued health monitoring and freshness.
