This species of Jungle Cats live in the Jungle in trees, where they hunt black-colored tree mice that live on branches and have black, brown, white and sometimes tan fur to blend in with their surroundings. Males use the multi-colored tails of other female Jungle cats to find potential mates.
A part of the jungle catches on fire, creating a forest fire and ultimately causes a group of the Jungle Cats to evacuate and escape their habitat to safety.
The cats end up in a desert that is close to the Jungle, but unfortunately they lose their way and are unable to track their way back, due to the wind blowing the scent of their path and their paw prints.

While some of the cats from the original group of Jungle Cats are unable to survive in the desert and die, a small number of them manage to reproduce and got energy through hunting and eating brown sand mice. As their diet changed, the traits needed in order to catch them changed as well.
While some Jungle cats had stubbier, shorter legs others had long legs which helped them catch sand mice and travel the desert quicker. This aided the Jungle cats with longer legs in catching mice, while the stubbier-legged cats were less likely to catch food and thus starved.
Additionally,  Jungle cats had multi-colored fur, while the new generation began to grow solely tan-colored fur that blended in with the sand. This is because the cats with the most tan-colored spots in their fur were able to hide the best from their predators (desert lions) and survive, AS WELL as blend in from prey to hunt.
This also altered the mating ritual of the Jungle cats, since now there were no longer multi-colored tails they instead began to identify potential mates using the slender legs and tan fur of the females.
One day, the Jungle cats that adapted to the desert, Desert cats, ended up interacting with the original Jungle cats through a path that formed between the desert and the Jungle. Although there was no conflict for food, due to the difference in fur color and mating preferences they were unable to breed with each other, thus isolating the new Desert Cat species among the cats that lived in the desert, from the Jungle Cats.
