Our cat says "woof" back. Poor thing when a tiny kitten on our doorstep was raised with our two dogs. He never understood he was not a dog, actually gives out a little bark when demanding my attention. Back when our dogs were protecting our abode and would run down the driveway to greet/confront visitors, the kitten would run along between them, meowling his best imitation of a bark. He still is a kitten, sort of permanently. We clipped his tomcathood just a little early.
I had a friend in suburban Chicago who plucked a teensy, half-drowned kitten out of a flooded gutter. Wise mother that she was, she recognized that the kitty needed self-esteem -- so she named it Vlad the Impaler.
