PrettyLitter's Health Monitor

PrettyLitter was designed with proprietary health monitoring technology to help signal some potential health issues early before you may even notice symptoms in your cat. Specifically, PrettyLitter reacts to certain urinary elements such as levels of acidity and alkalinity to make color changes visible to the naked eye or show blood.

We save cat owners money on potential vet bills through early detection. Help avoid a rushed trip to the emergency veterinarian by keeping daily tabs on your cat’s health. PrettyLitter has helped many cat parents catch early signs of abnormalities like urinary tract infections, bladder crystals, and kidney tubular acidosis.

Blue = High Alkalinity

Blue crystals

Alkalinity outside of the average range may be present if your cat has certain types of urinary tract infections and increase the risk of struvite crystal/stone formation.

Dark Yellow/Olive Green = Typical

Dark yellow crystals

When the PrettyLitter crystals appear dark yellow or olive green, your cat’s urine is in the typical pH range.

Orange = High Acidity

Orange crystals

Acidity outside the average range may be an early sign of metabolic acidosis or kidney tubular acidosis. Calcium oxalate crystals can be more likely to form in acidic urine.

Red = Presence of Blood

Red crystals

The presence of blood may indicate Feline Lower Urinary Tract Disorder (FLUTD), bladder stones/crystals, kidney stones, bladder inflammation, certain types of kidney disease and clotting disorders. In rarer cases it can also mean bladder cancer or an internal injury. PrettyLitter does not detect trace amounts of blood on a micro level.
