Pata Zoo In Bangkok, Thailand

The zoo first opened in 1984 and has remained a popular attraction for the Thai people ever since. It does not appear on any 'Tourist tour' as far as I am aware. The zoo nearly closed in 1992 when a tragic fire caused the death of many animals held on the 6th floor. Those on the
7th floor survived.
Over the years a huge variety of different species have been held here. The question must be asked. What happened to the Polar Bear, the Pigmy Hippo, Clouded Leopard, Elephant and others?
