It's always a great pleasure to build worlds based on criteria provided. Alas when I try to build a world on my own I'm all over the place. Bouncing ideas with people keeps me grounded. I'm usually good at seeing the pattern that people are subconsciously looking for.
I actually was inspired in the lapping scene from a book called 'Jennie' by paul gallico. It's about a boy who turns into a cat and another cat starts to teach how they go about things in their world. Quite possibly one of my all time favourites... Except it suffers from the worst ending trope possible that's was quite common in kids books...
I'm pleased with how Arcade anomoly is going too. Always wanted to write about a person experiencing cat girl world :)
