Did you know that even bunnies have lovers quarrels?! It's true. Lina Rue sometimes steals Davy's treats or violates him in unmentionable ways. That causes problems for this husbun.
(Don't worry, Davy isn't dead. He is just ultra relaxed! That's called the bunny flop. They just plop over out of nowhere. You will be hard pressed to find a cuter scenario. I really mean that. It's a fascinating thing to observe when out of what seems like nowhere the bun decides to plop over on its side and take a nap.)
For other species it usually means something very different when that event happens. Yet for a bun, that just means they are ultra happy and feel safe. For a prey animal to relax like that means that it doesn't sense an ounce of danger.
