Health IN SECONDS.
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.
