If you want to stop cats from skulking around your house and causing mischief, soak a sponge in vinegar and place it in the problem area. Cats hate the smell and won’t go near it. If your cat is marking its territory inside your house, spray the area with vinegar to get rid of the smell and prevent recurrences. Also, 1-part SAFARI® White Spirit Vinegar to 3-parts water poured over a pet urine stain and blotted with a clean cloth will neutralise the order.
