I was trying to remember if it was "do cats eat bats" or "do rats eat bats." Turns out it was cats, and once again reality is stranger than fiction. :D

“And here Alice began to get rather sleepy, and went on saying to herself, in a dreamy sort of way, 'Do cats eat bats? Do cats eat bats?' and sometimes, 'Do bats eat cats?' for, you see, as she couldn't answer either question, it didn't much matter which way she put it.”
