Fearless tourists are taking up a slithering spa treatment with a difference - by receiving massages from four giant pythons. Visitors to Cebu City Zoo in the Philippines can undergo a ’sssspa treatment’ from the deadly snakes which measure up to five metres long. The four Burmese pythons slither across participants for up to 15 minutes - and the snakes are fed 10 chickens beforehand to curb any hunger pangs. The terrifying treatment is free for zoo visitors, and is apparently beneficial because the snakes’ slithering is therapeutic and calming. Zoo bosses also claim the flickering of the snakes’ tongue on skin mimics a tickling sensation.
