Tigers

Tigers eat fish and other animals bigger than them but what if those animals were hard to find. If the tiger's normal meal is going extinct then they will probably have to change their diet to plants. Also since there won't be any trees they will have to shed more and there won't be enough precipitation for rain and drinking water. The tigers wont need stripes because it wont be eating animals so it wont have to hide and catch its prey. It also wont need claws, sharp teeth ,or a long tail because the claws are used to catch animals to eat or climb trees,as for the teeth they wont need to be sharp because it will eat plants, and finally it wont need a long tail because it doesn't need to run after food anymore.
