Lazy or Benevolent?

In addition to Oscar our cat, we have another animal friend that likes to hang out in our backyard, near the garden specifically. Our neighborhood is hopping with them--rabbits. So far our garden fence has been working well, but there's a little one enjoys nibbling the clover that grows amongst our crabgrass.

Last week I peeked out at our cat sitting out in the yard, as he does most days, and saw this:
What??!! Aren't cats and rabbits mortal enemies? Either my cat is 1). ultra-lazy or 2). just generating some good karma. I'm hoping our Buddhist-tendencies toward benevolence are rubbing off on him too.
But seriously Oscar, don't let me catch you behaving like that if we ever find mice in our house.
