What Does Your Cat's Urine Color Mean?

Most standard cat urine color charts rely on visible symptoms like dark yellow (dehydration) or red (blood). However, many feline health issues are invisible to the naked eye. 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, the PrettyLitter formula evolves the traditional urine chart by reacting 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

Blue may indicate a pH consistent with urinary infections or higher stone risk. Highly alkaline urine can increase the risk for struvite crystal/stone formation.

Dark Yellow/Olive Green = Typical

Dark yellow crystals

Dark yellow / olive green indicates urine within a typical, healthy range. This is the baseline color for a healthy cat on the PrettyLitter chart.

Orange = High Acidity

Orange crystals

Orange may indicate a pH consistent with metabolic acidosis or kidney tubular acidosis. Calcium oxalate crystals can be more likely to form in acidic urine.

Red = Presence of Blood

Red crystals

Presence of blood, which 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.

Our Veterinarian in Chief says: PrettyLitter will help you monitor your cat’s health in detecting abnormalities in your cat’s urine by testing acidity and alkalinity levels and the visible presence of blood. PrettyLitter cannot detect every feline health issue or prevent or diagnose diseases. A diagnosis can only come from a licensed veterinarian..
