Royal Canin Hematuria Detection Litter Granules for Cats 2 x 20g

Notify Me When Available

HEMATURIA DETECTION by Blücare is a white litter granule that can be sprinkled over a cat’s litter tray. If the granules change colour from white to blue when the cat urinates on them, this indicates the presence of haematuria and signals to the pet owner that it is time to take their cat to the vet.
HEMATURIA DETECTION has been designed to ease the at-home monitoring for the detection of blood in your cat’s urine. 

Cats tend to hide disease symptoms and can show few or no early signs of illness. If a medical condition goes unnoticed, treatment options may be limited or your cat may require expensive long-term care. That’s why your vet may prescribe Royal Canin HEMATURIA DETECTION by Blücare.

Most urinary conditions tend to re-occur after one episode - in fact, approximately 50% of cats that experience one episode of feline lower urinary tract disease (FLUTD) will have a recurrence.


  • A urinary test in the comfort of your cat's home environment

  • Easy to add granules to your cat’s existing litter
  • Allows detection of blood in the urine, even small amounts invisible to the naked eye

  • Results visible within seconds and remain visible for 48 hours

Royal Canin HEMATURIA DETECTION by Blücare can be used with most litters available on the market. For best detection and interpretation of the results, a clay- based (bentonite) clumping litter should be used.

If the granules are WHITE or YELLOW, this is a negative result and no blood was detected in your cat’s urine. When the granules are BLUE, consult with your veterinarian as soon as possible, as it means blood is likely present in your cat’s urine. In some cases with concentrated urine that also contains blood, the granules might appear to be GREEN in colour which may also indicate a positive result and your veterinarian should be consulted.
