In the Land of Hauilkm Humans are no more. It is the Year 4250, and after a major environmental disaster, only a few survived. These Canines & Felines are descendents of animal experiments, where their great grandfathers & Great grandmothers suffered horrific pain and suffering in tiny cages for the "benefit" of human health.
Back in the year 4000, many scientists understood that soon the human race would end. With that in mind they decided to let go of over two thousand innocent animals they had used for experiments back in the wild. And these animals did not only survived, but they flourished. These animals passed on radiation, antibiotics, hormones and more to their offspring. Making many of them being born with deformities.
The young that survived seemed to have good mutations, things that will help them survive. They even seem to become bigger, stronger, and smarter and the years went by. And by 4250 the animals have evolved into intelligent species who could live in a social hierarchy or leaders and followers.
Some of these dogs & cats now have extra limbs, faces and tails. Some seem to glow with the many colors they come in. Some can even fly with wings. While others can read your mind, or move a stone with only their brain power.
