Recently, I noticed that the cat was chasing a rabbit in our backyard.  So, I opened the door to yell at the cat to leave the rabbit alone.  The next thing that I know, the cat has chased the rabbit into the house.  But, since the cat was better at navigating stairs than the rabbit, the chase quickly ended.

When I caught up to them, both the cat and the rabbit were exhausted.  So I picked up the rabbit and put it outside.  This whole thing ended better that I has anticipated.
