Is this the world's worst zoo? Shirley the orangutan allowed to become a chain-smoker by heartless attendants
* Crocodiles live in waterless enclosures and big cats live in tiny cages in Malaysian animal park
A trip to the zoo should fill any animal fan with a sense of joy wonder, but in Malaysia the experience inspires revulsion.
Crocodiles struggle in waterless enclosures while lions and tigers are trapped in boxes barely big enough to house them, leaving no room to roam around.
But worst of all is the plight of Shirley, a 25-year-old orangutan, who competes with cage-mate Abu for cigarette butts thrown by tourists to satisfy her smoking habit.
Puffed out: Shirley the chain-smoking orangutan is typical of the horrors to be found in Malaysian zoos
Hungry: Shirley spends her days tearing apart drinks cans and food wrappers thrown by tourists as she searches for more food and drink
The government-run zoo in in Johor Baru has erected a 'no smoking' sign but that will do precious little to stop the sad practice while attendants turn their backs on it.
Shirley spends much of her sad existence tearing apart drinks cans and chewing on food wrappers thrown at her by visitors.
She regularly reaches through the bars of her cage to beg for cigarettes.
No room: This tiger is kept in an enclosure that affords barely any room for exercise
Indifference: Zoos in Malaysia were given six months to clean up their acts in October but when the June deadline passes precious little progress will have been made
Not up to standard: The entrance to Johor Baru zoo in Malaysia where Shirley has been allowed to cultivate a smoking habit and animals are kept in appalling conditions
Ignores regulations: Some of the animals at Johor Baru zoo are made to perform for visitors despite that being outlawed
