Kit4Cat is a patented hydrophobic litter that keeps cat urine on top, making sample collection quick, clean, and stress-free. It smells and feels like regular sand and features a natural, non-toxic repellent coating cats readily accept. Designed for veterinarians, technicians, and cat parents, it enables passive urine collection without invasive procedures like cystocentesis. The kit includes everything needed to collect a urine sample and comes in a 900 g bag (3 x 300 g packs), ideal for at-home or in-clinic cat urology needs.
