Welcome to my world…my new male Basenji started marking when he walked in the house and then my Rocky boy decides he needs to mark too. I've been walking around with a spray bottle of Simple Green and rags - not to mention yelling, "Go outside to pee!" a lot. Finally, today the p***ing contest stopped. Whew. (I didn't mention I have four females and one foster female who is not spayed!)
Watch the vinegar, I used it and the carpet smells like a salad when the air is humid. Yuck. I've been steaming with simple green, then rinsing well with water and 1 cup of Febreze Concentrated Fabric Freshner. I buy it in the gallon size.
