I'm like to introduce you to a world where humans have existed. This world is totally populated by anthromorphic animals. Anthros can be any animal you want. They also live just like humans do; they wear clothes and the like like humans do. One very important thing is all anthros are barefoot. Shoes & socks were never invited.
Now for chapters you can have magic of any kind or super science. You can have anthro animals becoming feral animals through magic or science or just casting magic.
You can have them have sex or giving birth.
You can also have them voring each if you like.
Now I hope you have fun with this story.
Till next time, Raven Cross signing out.
