(CNBC) - Pets are big business. According to CNBC, Americans spent 72 billion dollars on their pets in 2018.
From tech gadget toys to specialized veterinary care, humans now splurge on dogs and cats the same way they might on themselves or their children.
It's part of a trend called the 'humanization' of pets.
And a big driver behind this movement? Millennials. As some delay having children and starting families, more and more end up treating their pets as surrogate children.
