When you decide to take on a pet, you're giving yourself a huge responsibility. While it's no skin off your back to set out a bowl of food and water for an animal and keep them indoors, to your pet, it means the world.
Because for the most part, you're keeping that animal from death. You provide them shelter. You make sure they aren't getting chewed to bit by any parasites and regulate when they do. You give them love. You give them structure. In return, they adore you and are cute and unflinchingly loyal because animals are better at that thing than human beings are.
