Personal hygiene is one of the most important parts of our daily lives, and we aren’t the only ones who love it. Spend any amount of time with a house cat and you will notice that they spend more time grooming than anything else. Part of this is because it’s advantageous to stay clean. But part of it is because personal grooming and hygiene feels good. In fact, we know that good personal hygiene has an impact on how we feel and on how people feel about us.
