Brave little bunny

There is a rabbit that visits my back yard in Carson City in the mornings.  He/she is sitting out there now.  I'm not sure why, or what's so appealing about the yard, but there you go.  He looks cold just sitting there, all bunched up with his front paws tucked under his belly.  The dogs are completely unaware.  The are resting peacefully on the couch.  Sometimes they notice and give chase, but at the moment our bunny is safe.  I suspect there are more than one living in the hill behind the house.  It makes me wonder what life must be like for them.  Do they have rich emotional lives?  Do they care about much?  How simple their lives must be.
