People like coffee and people love cats, so together they make the paws that refresh at a London cat cafe that is so popular it's booked out until June.

Lady Dinah's Cat Emporium, on the fringe of London's financial district, is cashing in on an idea first popularized in Japan to allow stressed-out workers to wind down by stroking a cat while sipping a cappuccino or latte — or tea, if you prefer.

"The idea is you can come have a peaceful lunch or high tea and be surrounded by cats. If you're lucky, one of them will fall asleep on your lap," said Anna Kogan, an investment banker who is co-owner of Dinah's along with Australian Lauren Pears.
