Cats are finicky creatures so it’s not surprising it takes very little to get them mad at you. Fortunately, once you know the four major activities that cats dislike, you can (hopefully) avoid them to maintain peace in your home.
First, cats are social animals (whether they show it or not), so they like your presence just so they can have someone to ignore. Second, cats dislike dirty litter boxes just like humans dislike dirty restrooms. So keep your cat’s litter box clean and keep them company at all times.
