the runaway bunny

Once there were two rabbits who lived in a cage.
Once a week they got to visit the great outdoors for exercise.
But one Saturday they decided not to return to their place of living. Every time the big bad human moved to catch them, they hopped. Fast. The big bad human would sit very still, tempting them closer. They would come, put their front paws on her jeans, then before she could blink, they would flip 180 and hop away. They spent the night in the big outside world. And the next morning, there was only one rabbit.
The big bad humans surmised that poor little Sally must have been eaten by an owl. There were no holes that she could have crawled out of, and there were no signs of a struggle. It had to have been a bird that swooped down in the night and took her away.
Sunday went by, then Monday.
On Tuesday morning, this what the big bad human saw:

Sally has hopped in the garage. She's hopped up and down the front ramp to the porch. She's hopping all over the front yard. But she will not hop back into her cage.
She is a runaway bunny. :(
Meanwhile, poor little Thumper sits all alone.
