My cat is still quite young, but she's already had her fair share of hunts. Examples are the time she swiped a cranefly out of the air and the time she outmaneuvered a giant house spider and ate it on the spot. She often chases my pet bunny, but she's never hurt her or anything, the tables are often turned, my bunny is intelligent and friendly, but let's put it this way, she's no pushover.
The cat is intelligent and social, too, but that's to be expected, I'm more impressed with the bunny because she's Einstein by rabbit standards.
