Interesting AU. I don't know where your Muse picked the idea up but it is definitely strange. It is a good story though! :) I think you did well with choosing the animals.

What a unique story - I loved it. I hope you are planning to write some more

This has to be one of the strangest M7-AUs I've ever read. I'm not sure if I really like it, but it's an very interesting idea. The idea of JD as hyperaktive puppy made me laugh, because it fits somehow :-)
