Airbnb Experiences, the activities arm of the home-sharing platform, offers travelers many things to do in Lima, Peru. They can learn to cycle around the capital on a bamboo bike ($32); make ceviche in the home of a local ($62); and spend 90 minutes with Otto, the skateboarding bulldog who set a world record for the longest human tunnel traveled through by a skateboarding dog (picture a line of participants standing with their legs wide, creating a passageway for the rolling canine).

In the three years since Airbnb introduced its experience bookings, it found some of its most popular involved animals. On Thursday the company is introducing “ Airbnb Animal Experience s ,” an expanded and stand-alone category, much like its existing “Food and Drink” and “Sports and Outdoors” categories. The new animal division will have an ethical focus.

“We realized people want to reconnect with animals,” said Mikel Freemon, the head of animals at Airbnb Experiences. “We wanted to fulfill that urge in a responsible way.”

The announcement comes at a time of increased scrutiny of organizations offering animal and wildlife experiences in tourist destinations; on Wednesday, TripAdvisor announced it would end its practice of selling tickets to events or attractions that breed or buy dolphins, whales and other marine mammals. Indeed, there is growing concern worldwide over the level of regulation of zoos, wildlife parks and other animal refuges, particularly in developing nations, which may potentially attract travelers to situations in which the animals are abused for their entertainment, or worse.
