Now, your cat’s first line of defense is you

At Royal Canin we believe pets make our world better. That is why our purpose is to make a better world for pets. In addition to creating premium, complete and balanced nutrition solutions we have also studied, over the last 50-years, a holistic approach to pet health, and have identified more ways that we can support pets, their owners and the professionals who care for them. Through research, science and innovation, we are now taking our first step towards providing this holistic approach through the launch of monitoring tools and services that help pet owners, under the guidance of veterinarians, identify potential health needs in pets that may be supported through nutrition. HEMATURIA DETECTION by Blücare is our first step in this evolution. This tool has been designed to support you by easing the at-home monitoring for the detection of blood in your cat’s urine.
Royal Canin Hematuria Detection, technology by Blücare, is not a substitute for veterinary diagnosis.

What if you could unlock your cat's health secrets?

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, technology by Blücare – litter granules for detection and on-going monitoring of blood in your cat’s urine.

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.

Using your HEMATURIA DETECTION by Blucare in 3 easy steps


Spread the granules over the litter and wait for your cat to urinate.


Inspect the litter box after your cat urinates. If granules are WHITE or YELLOW, the test is negative. If they turn BLUE, the test is positive, as it shows the presence of blood in your cat's urine.


If the granules have turned BLUE, contact your veterinarian as soon as possible to discuss your cat’s results and what you can do to maintain their health.

Test results may vary based on conditions of use and other factors such as a cat's diet and medication.
Each test has its limitations, false positives, and false negatives. Accuracy of results is not guaranteed.
