They are also cats. Why are lions dirty and tigers clean?

Tigers are so clean. First of all, lions live in the savanna, which is dusty, with short rainy season and long dry season, and it is dusty everywhere; Tigers live in tropical rain forests, subtropical jungles and coniferous broad-leaved forests in cold temperate zones, with abundant precipitation, less dust, less bare land and more grass and forests. Secondly, the lion's fur is grayish yellow, which blends in with the environment and feels covered with dust; Tiger's black, white and yellow stripes, with bright colors and strong contrast, are suitable for mottled light and shadow formed by light shining into the forest. Finally, lions don't like to go into the water and are not good at swimming; Tigers especially like swimming. To sum up, the tiger looks cleaner than the lion, and it is indeed cleaner than the lion.
