Thanks everyone. Yes, she does use a covered litter box. I never thought about that being a possibility. Mollie is the sweetest cat - she's one of my 3 "babies". The other two are Peach and Maggie. I got Peach & Mollie last summer (June) and Maggie in September. She was a stray that had been at a neighbors for a few weeks before I seen her. At first I wondered if I should actually take her home, but when I picked her up, she just acted like I was her person..
