One-year-old Sumatran tiger Dumai plays with its scratching post tagged "Aussie Dog" in its enclosure during a birthday breakfast at Sydney's Taronga Zoo October 22, 2004. The cub, one of three born in October last year, is a valuable addition to the zoo's tiger breeding programme as Sumatran tigers only number about 400 in the wild. REUTERS/Will Burgess WB/FA
