And although cats want their own turf to scratch and mark, they might still want to scratch other areas . . . areas that smell like . . . you. Cats love to scratch couches and chairs that you use for a few reasons, the key one being: just like they create a “group scent” with other cats they live with, they probably want to do the same with the other mammals in the home . . . especially the big, hairless ones who provide them with food and love. Your cat is trying to comingle her scent with yours to show the ultimate in cat sharing: co-ownership of territory.
