TEACHING A KITTEN WHAT A MOM CAT TEACHES?

Some cats bury their business, others do not. Many that have a more dominant personality will leave their business uncovered, sort of as a sign that they are *here* and don't need to hide. So that's may be more of a personality issue than a training one. Not sure what to suggest on the grooming issue - just keep doing what you're doing, and be sure to brush/comb her as cats really do need to groom to keep their fur from matting, etc.
