With the Pidan Tofu with Occult Blood Test Particles Cat Litter, you can easily keep an eye on your furbaby’s health. The test particles will turn blue when there’s blood in your kitty’s urine, so you know if you need to call the vet. The litter makes cleaning the box su-purr easy, too. It’s made of organic pea dregs and features multiple pellet sizes to enhance clumping for easier cleaning. The different particle sizes promote high absorption rates and help to trap liquids to decrease tracking and keep your home cleaner. The raw tofu material helps to reduce dust to make the litter box healthier and cleaner for your cat, too. Since this formula is water-soluble, it’s safe to dispose in the toilet for convenient and eco-friendly cleanup. Purr-fect!
