If you’re wondering when dogs first became pets, you’re not alone. Many breeds evolved from wolves that humans kept as their own. Dogs were bred to have certain conformational characteristics that helped humans outcompete Neanderthals. These dogs became domesticated in a short period of time and are now popular pets worldwide.
Pigs and cats are close contenders for the title of cleanest pets in the world, and their reputation for keeping themselves clean is well deserved. Cats spend up to 50% of their waking hours grooming and licking themselves. This can be very helpful for those of us who would like to keep our homes as clean as possible.
