Zoos around America have been running 'animal sex tours', providing champagne and chocolate-covered strawberries by candlelight complete with a talk on animal sex sometimes along with a live preformance depending on the zoo and the animal's mood.
Guests are told about a pig's corkscrew-shaped appendage, whales' 10-foot penises, the propensity of manatees to have orgies regardless of gender and how porcupines can only mate - very carefully - during one 4-hour window each year.
Marketed under names such as "Jungle Love" and "Woo at the Zoo" the concept stated with former penguin keeper who, after observing her "bowling pins making love" suggested to her boss that others might be interested in animals mating.
