Pets are admittedly a big commitment. Depending on the species of the pets, they'll probably live a long time and require a lot of day-to-day care over their lifetime. But if the Internet has taught us anything, it's that pets provide us with endless giggles at all the silly things they do, whether cat, dog or more exotic pet species. Animals can inspire a lot of joy; from their silly physical antics to their goofy personality quirks.
But pets have been increasingly proven to promote happiness in a very tangible way. For example, services are springing up around the United States that pair vets -- the veterans of recent wars, that is -- with dogs that need a loving home. These animals provide the sort of unquestioning and nonjudgmental companionship that many veterans suffering from post-traumatic stress disorder (PTSD) find hard to manage with human confidantes. And that sort of therapy can definitely boost happiness levels.
