This is hilarious! I have puppy sides and kitten sides, mostly. Every so often I've been known to act like a very dumb, whiny little pet fox.
I saw a video yesterday with a delightfully dark fantasy of being a slave who willingly receives poison from his mistress just to please her (and die for her!), so if I were a pet goat, or something, I could be a cute, stupid companion for a little while, and then, when my owner so declared... dinner!
Along those lines, perhaps we can imagine Mistress and slave both being non-human creatures...
Oh, what foolish little vermin we can be
