Pandas do not like company, even when it comes in the form of other pandas. They live alone until it's that 2-3 day slot a year when the females ovulate and instinctively holler at males in the area to let them know sex is finally on the table. Considering the elusive nature of breeding in their natural habitat, you can imagine how difficult it is to encourage them get it on in the zoo. Another massive stumbling block is the sad truth that male Pandas born in captivity dont actually know what to do when it's that special grown-up bear time. So, enter stage left, the fluffers. With little prospect of success, they will try to help their confused charges get going by showing them how it's done in the wild. Donning costumes and playing out the scene themselves is seen as way beyond the call of vocation so the fluffers rely on ready filmed panda porn. The fluffers are keepers at the zoo and for the other 362 days of the year it's presumed they're looking after the animals rather than hunting down more stimulating footage for the mating season.
