Pets are amazing. Furry, fluffy four legged serotonin-bombs. Whether canine, feline or the exotic kind, they add extra meaning to our lives. A head-bump from a cat, leaning in with a purr, or a goofy grin from a dog, tongue lolling to the side with a tail wagging derilously with joy. They lift our spirits, keeping us active, healthy, happy and more loving.
