1. Empty your cat’s litter box.

2. Wash it, rinse it thoroughly and dry.

3. Some cats will urinate in an empty box. Others need some form of “litter” such as styrofoam packing peanuts, dried lentils, cut drinking straws, unpopped popcorn kernels or clean plastic pebbles/gravel you purchase from an aquarium shop. Anything that your cat accepts and is non-absorbent will do. You could also purchase a non-absorbably litter called “Nosorb” or “Kit 4 Kat” from our hospital.

4. After your cat urinates in the box, remove the packing peanuts and pour the urine into a clean, dry container.

5. Transfer the urine into a clean (unused) resealable plastic bag, plastic food with a lid or a jar with a lid. The container or jar should be washed in hot soapy water and air-dried before use. Seal the bag or place the lid on the container or jar.

6. Store the urine sample in the refrigerator until you are ready to bring it to our hospital. Refrigeration inhibits the growth of bacteria in the urine, which could cause false laboratory test results.
