    How our test helps

    Signs of kidney disease are often hard to spot

    Tracking your cat’s bathroom habits and water intake can be tricky. With a swipe of their gums, our kidney test measures their urea level through a color-scoring scale, so you can get clear and easy-to-understand results.

    Learn what urea levels can indicate about your cat's health.

      Why kidney health matters

      The risk of kidney disease goes up with age

      Your pet has a higher risk of undiagnosed chronic kidney disease if they are 7 or older. Regularly testing your pet can help you take control of their kidney health and catch changes at home to give them a long and happy life.

        How it Works

        Testing your cat’s kidney health from home

        • Take out a test strip

          Each test comes with two strips, just in case your precious cat thinks the first one is a snack.

        • Rub it along their gums

          Nothing crazy. You just need to get it wet. Sliding it around for about 5 seconds should be enough.

        • Wait 2 minutes & get your results!

          Match your cat’s sample with the color-scoring scale on the box to get your results and guidance on what to do next.

        Kidney Test FAQs

        What is the function of our At-Home Kidney Health Test?

        • The Petivity At-Home Kidney Health Test for Cats measures urea levels in your pet’s saliva in just two minutes, helping identify changes in kidney health.

        • Urea, a waste product from protein breakdown, is a crucial indicator of kidney function. If you notice elevated levels on your pet’s test, we encourage you to speak with your veterinarian about further testing.

        Is it a substitute for blood work?

        • The Petivity At-Home Kidney Health Test for Cats and Dogs complements regular lab work but doesn't replace it.

        • Elevated results suggest consultation with a vet for further testing. High levels of urea in your pet’s saliva can result from various conditions.

        How do I administer the test?

        • The Petivity At-Home Kidney Health Test is a saliva test. To collect a sample and get your results, remove one of the test strips from the package, and rub the pad of the test strip along your cat’s gumline for 5 seconds on each side of the mouth to get it fully wet.

        • Start a timer for 2 minutes. When time is up, immediately compare the color of the test strip pad to the color-scoring scale on the test package to get your Final Result and our recommendation.

        • Do not leave the test strip unattended in your cat’s mouth. Avoid damaging the pad on your cat’s teeth or tongue. If the pad does become damaged, repeat the test with a new test strip.
