present and future tiger

My animal is a tiger, in its present form it lives in a rainforest.Full of trees and tigers have stripes.Orange And black stripes on its body and tail.Face is orange With whiskers.Lots of water sources and fish to hunt. Very long ears to hear from far away. In its future form(thousands of years away), the rainforest now is a desert/savannah.Tigers turn yellow to blend in. Very few water sources to hunt fish and drink water.Full of cobwebs and very hilly.Tigers lose stripes and ears get shortened to blend in.No more whiskers to blend in.
