Omigosh what a pair they would be -- especially when Mephisto's main animal of choice is a small dog! Which he turns into pretty often, since he's living with Yona as her pet dog as an excuse to live somewhere rent free... he has weird hobbies...

I'll be putting up an open log soonish I think that'll have a few exploring prompts, but I can put up a closed prompt for catdog shenanigans while exploring! Maybe somewhere somewhat safer like Flona Cove...? But they could still get carried away by a giant bird or something, which could be a funny way to out each other as not actually being a cat/dog.
