"I paid $30 for this," he said. "I never pay for anything. But let's be honest, I'm doing this because I'm a world traveler, and I don't like to work. I'd rather be supported."
Whatever the reason, Barkley said, "cubs are driving this cougar trend."
Gosse of the Society of Single Professionals said they had to cap the number of cubs who could attend the first international singles cruise sponsored by the Singles Travel Co. in early December. There weren't enough cougars registered.
As cougar and cub relationships become more widespread, businesses are lining up to take part.
Cougar dating sites have already hit the Internet. Cougarncubs.com claims "dating cougars ... has never been easier or as exciting."
Cougarsinternational.com, Cougared.com, DateACougar.com, GoCougar.com and CougarPersonals.org also claim to help lovers of different ages meet.
Shari Weisman, director of marketing for Cougar "N' Cubs, estimates there are at least half a dozen quality cougar-dating sites.
"It's groundbreaking, growing and getting profitable," she said.
Her company just advertised a cougar cruise that will launch in February. Within a week, more than 100 people made reservations.
What's more, there are cougar events organized by the Society of Professional Singles coming to Arizona, San Diego, Australia, Canada and the United Kingdom.
"Cougars are coming to a city near you," Gosse said.
