Just got a new kitten. She's probably about 6wks old give or take. My landlord found 3 of them under a barn about a week ago. He brought one for me to have for my young kids. First night here, kitten was very scared and skittish of course. It had an accident on my couch. I cleaned it the best I could and showed her where the little box is (have a 4mth old kitten too). The new kitten does NOT go to the litter box at all. Only my couch. Both sides. I am cleaning it CONSTANTLY and its not working and its really starting to smell. PLEASE HELP!!!
