This goes here.

River decided that all of her hay NEEDED to be placed in her 'spaceship'/ziploc cozy bunny sleep system/litter-box digging deterrent.  I was making dinner when I heard a ridiculous amount of hay rustling coming from the living room and this is what I saw...

I moved the hay back to where it belonged.  River, being the stubborn little bun that she is, decided to move it all back to her spaceship...two more times.  She's currently waiting until I go to bed before moving it again.  Oh, bunnies!

Don't play with your food!

This was the face that greeted me first thing in the morning.  For a moment there, I was wondering if she was nesting (even though she's spayed) and if I needed to make a vet appointment.

I soon came to find out that Big Human gave River a large handful of hay to distract her from her favorite game of "bunny jacks" (where she'll pick up a piece of hay then drop it while simultaneously seeing how many times she can dig at the ground before it hits the floor).

River was then inspired to create a new game...

This new game consisted of racing in a circle around her cage while picking up more hay with each successive lap.

This game went on for 5 minutes.  She's looking pretty proud of herself here and is preparing to make another lap to go for a new high score.
Simon is intrigued by her antics while I'm wondering exactly how much hay River can cram into her mouth at once.
(Note:  That white blob is to protect your eyes from funkified litter box--no one really wants to see that.  You're welcome.)

She managed two more laps before she thumped, came to a stop and pointed her nose to the sky.  I abruptly ended her game at this point because a bunny pointing their nose in the air usually means that they can't breathe.  I gently yoinked the hay bundle out of her mouth...

And River collapsed exhausted, but with a new-found appreciation for why we don't play with our food.  She had a wicked case of cotton mouth and I was picking tiny bits of hay out of her mouth for a short while after.
You'll be glad to know that River has not attempted to go for a new personal record in this little game of hers.  Lesson learned.

Clever girl!

River made herself a hay mattress.

Near as I can figure, this is what she did:
1.  Pull out all of the blue cloth from the ziploc container and set it aside.
2.  Collect 90% of the hay in her cage and transfer it to the ziploc.
3.  Cover the hay with the blue pieces of cloth.
4.  ???
5.  Profit (way more comfy sleepy-time).
She was not a happy camper when I dismantled her creation.  I was worried she was nesting and I wanted to test to see if she'd do it again (as a spayed female, that's a cause for concern doing something outside of her normal behavior) and I didn't want her wasting all of her hay as bedding.  She hasn't had a repeat performance, so at least I know she's healthy and learns quickly.
