飞猫是天坑溶洞群的特有动物，学名叫鼯鼠，又叫“六不像”，脸面似狐，双眼如猫，尖嘴类鼠，耳朵像兔，脚爪若鸭，尾同松鼠。它靠前后腿之间宽大的翼蹼能在绝壁和大树之间滑翔飞行，最大的头尾长度能达到1米、体重7斤多。这种动物很怕羞，昼伏夜出，加上日益稀少，要亲眼看到活生生的飞猫并不容易。[视觉中国 向航 摄]
Flying squirrels can glide between trees depending on a furry parachute-like membrane that stretches from wrist to ankle. They weigh more than 3.5 kilograms, and larger ones measure more than one meter in length. They are shy and nocturnal, which means that, in addition to their scarcity, it is very difficult to see one living in the wild. [Photo/VCG]
