You don't want to deny Po the pit viper his regular morning cigarette - he's guaranteed to throw a hissy fit.
That's because the three-year-old reptile from Taipei in Taiwan has become hooked on nicotine, thanks to his owner Sho Lau's 20-a-day habit.
'He is very tame and one day when I threw a cigarette butt away he went for it and seemed to enjoy having it in his mouth,' said 33-year-old Lau.
'One thing led to another and before long he was having one cigarette in the morning and another at night.'
'He gets very agitated if I don't have any to spare,' he added.
