Tigers’ memory is just awesome. Imagine, tigers in general, have been found to have a better memory for several hundred times better than humans, primates, and other animals.

- Tiger Stripes are Unique
Each of humans fingerprint is different. Every little smudge singles of us out as distinct individuals among billions of other human beings. Even identical twins boast different fingerprints.

- 老虎的尿，聞起來像奶油爆米花
老虎的尿液中存在一種叫做2-AP的芳香化合物。而做爆米花的時候，糖和氨基酸在高溫的作用下發生反應（美拉德反應），反應產物中就有2-AP，它是其中一種氣味分子。研究者們在部分貓科動物的尿液裡有發現2-AP並形容這種物質聞起來就像“奶油爆米花味”。
下次吃奶油口味爆米花時，會不會想到老虎？

- 老虎只有在呼氣時，才會發出呼嚕聲
老虎也會發出呼嚕聲，不過與家貓不同的是，老虎只有在呼氣時才發出呼嚕聲。
- Tigers Cannot Purr
If a cat purrs, it makes a soft low sound in its throat to show that it is pleased. But this won’t happen to the tigers which are unable to purr. So instead, they show their happiness by squinting or closing their eyes.
