Most mornings, my big boy bunny does zoomies around the living room. He runs from one end of the house to the other end as fast as he can.
Every morning, my tiny girl bunny runs around doing zoomies and binkies when she knows she is about to get her breakfast.
When they aren’t running around like crazybuns, they have to always have their butts touching. If they are laying down, sitting, in the litter box, etc, their butts have to touch.
Here is my big boy (left) and my tiny girl (right). Having bunnies makes me smile every single day.

Shiva Kush. I found it once 10+ years ago and I haven’t had it since. It was a really good one for my long walks.
