Use a phone app to monitor / interact with your cat when not home
IP security cameras and pet cameras allow you to use a phone app to not only watch what your cat's up to when you're away but also interact with your cat in various ways.
Contrary to some stereotypes, cats want and need attention from their humans. It's just that they often want it in their own time and on their own terms. You also may want to pay attention to them for the entertainment they provide or to minimize the mischief they get into.
