I remember being taken to Johore Zoo when we were kids in about 1966.
At the time, we thought it was great fun going to the zoo. There was a gorilla who would clap for food and everyone liked seeing him. Nowadays, I realise that it was all pretty appalling. The gorilla had no more than a small cage to be kept in and had been trained to clap his hands to amuse the public. These weren't animals that had been born in captivity but were wild animals who had been trapped and put in the zoo. I do remember that the zoo was very smelly and unclean at the time. I think that I've told the story before about the three legged tiger. He had been trapped in the jungle for the zoo. By the time the trappers found him, his leg was in such a poor state that they had to remove it. This didn't stop them from exhibiting him as soon as he was well enough!
All these pictures come from our home movies so sorry they're not very clear. They show my brother feeding the gorilla, him clapping, the forlorn gorilla looking out of his cage and the three legged tiger. I hope the animals are better looked after today!
