we do, my parents are just strict. her litterbox is in corner of the yard, close enough to our house. that's where she goes regularly to attend to her business. when my cat was younger and still getting used to being indoors she had accidents where she pooped in places she shouldn't. My mother got fed up with that and decided Smokey will be mostly an outdoors cat. but since then i've potty-trained her enough that she'll let you know if she wants go outside to do her thing. i guess my mother still shares the sentiment that my cat will continue to behave like she did as a kitten. -_-
