Many cat owners are familiar with the unpleasant experience of getting their beloved feline in the car to go anywhere. Since most cats don't go for car rides often, your cat probably associates getting in the car with making a visit to the vet. Along with the anxiety your cat experiences, you may also have to deal with him urinating in the car. Even if you transport your pet in a cat carrier, the urine will almost always leak out onto the car seat.
Blot up as much of the urine with paper towels as possible.
Mix 475 ml (2 cups) of warm water and 18 ml (1 tbsp) of vinegar in a spray bottle. Spray the seat well until it is saturated. Let it sit for 10 to 15 minutes. The vinegar is a natural odour absorber that will neutralise the urine smell on the seat.
Blot the area well with paper towels to absorb all of the vinegar solution. Liberally sprinkle the seat with baking soda.
Mix 180 ml (3/4 cup) of hydrogen peroxide with 6 ml (1 tsp) of detergent, and apply it to the soiled area on top of the baking soda. Use an old toothbrush to work the peroxide solution and baking soda into the upholstery.
Allow the seat to dry completely, then vacuum it well. Spray the seats with a fabric refresher.
When transporting your cat, place a trash bag under the carrier to prevent urine from leaking onto the seat.
Test a hidden area of the seat before applying hydrogen peroxide to make sure it won't cause the seat's colour to bleed or fade.
