Burmese kittens & cats in Hillsborough, North Carolina

I have an adorable 4y black, short-hair, cat with two white spots on her. Her name is Midnight Elvira. She is a very sweet, affectionate cat who loves cuddles and belly rubs and has been living with dogs since she was 4 months old. The issue I have with her, and the reason why I want to re-home her, is for the last 2 years she has been peeing and pooping outside of her litter box. Primarily on the dogs bed. I have had to move 4 times in about 2 years, and I am also about to begin a very intense college program in January and I recognize that these issues are probably triggering her behavior. I recognize that despite my efforts (i.e., talking to vets, fluoxetine, daily cleaning, two cat boxes, attractants, deterrents, etc.), she would be happier living with more stability, with someone who can provide a single cat house, or maybe even living with another cat. She likes being outside with me on my porch but is not fully an indoor/outdoor cat.
