Pet Tech offers to keep animals safe, healthy and connected

In Silicon Valley and beyond, a growing number of startups are selling devices to keep pets safe, healthy, entertained and connected when their owners are away.

"Pet tech" entrepreneurs and investors see a big opportunity as pet ownership grows and owners show a willingness to spend serious money on their four-legged companions.

"The number of pets in the world is growing extremely fast and that opens up the market," said Peter Harrop, chairman of IDTechEx, a technology market research firm.

For owners who want their dogs and cats to be more active during the day, the Petcube Camera lets them see and speak to their pets, and play with them with a laser pointer.
