The Kit4Cat Cat Urine Sample Collection Kit lets you safely gather your cat’s wee for at-home or veterinary testing in the comfort of your home. This non-absorbent litter holds your cat’s urine on the surface for easy sample collection. Each kit includes two pounds of natural, non-toxic coated sand that looks, feels and smells like your cat’s regular litter. Your finicky feline can still go about her business in the comfort of her litter box. When she’s finished, use the included pipette and vial to collect her wee and then safely transport it to the vet or conduct an at-home test.
