I decided to finally write about where my characters live, why they are what they are, how much a taco is, ect.

Basics:
My characters live on earth... 10,000+ years in the future! All humans went extinct at this point, and the animals began evolving. The dogs were the first. Animals with hooves, scales, or feathers all haven't evolved yet, only some.

Hooved animals are quadrupeds, but other animals can switch from two to four legs. They dont need to wear clothes since most have fur. Some do it for fashion and others do it because they get cold easy. Trust me, in the summer you'll see more clothless animals than in spring.

Age and reproduction:
Animals like felines are able to live to around 60-80 years, and canines can live to around 70-90. Some animals still have babies the old fashioned and weird way, but most of them now just need a strong bond and boom! an egg!
