[originaltext] When two rare Sumatran tigers were born in Australia Zoo, nor

When two rare Sumatran tigers were born in Australia Zoo, north of Brisbane, they were sent to live with one of the keepers for the first few months of their lives. Giles Clark describes what happened when he took them home.
    Spot and Stripe were not the first tiger cubs I’d raised in my front room. I first did it about 20 years ago, when I was still living at my mum’s house in north London and was working at a small zoo nearby. I hand-reared numerous litters of lions and tigers there. Now I live in Australia and have worked at the same place in Queensland for 11 years— these are the first tiger cubs that have ever been born at Australia Zoo. Globally, a third of Sumatran cubs in captivity don’t make it to adulthood, so to ensure their survival I decided to give them round the clock care at home. I’ve got two children living at home, Kynan, the youngest, was particularly excited about the tigers arriving. I wasn’t worried about bringing them into my home with my wife and kids. These were cubs. They weighed about 2.5 kg and were so small that there was absolutely no risk. In four months, they were never going to grow any bigger than a medium-sized puppy. Just like puppies, they do things like chew on your slippers, but that’s about the worst you can expect.
