Dogs vs. Cats vs. Kids

According to the 2015-2016 APPA National Pet Owners Survey, the number of US households that own a pet breaks down thusly:
Cat 42.9 million
Dog 54.4 million
Dogs win – although in many households, such as mine, the dog peacefully coexists with the companion cat.
Either way, our furred friends have kids beat hands down. The same survey reports: “More than half of all Americans have a pet, and pets now outnumber children 4 to 1 in America.”
