I think it's funny that when I was at cuteoverload.com the other day and played a video of a baby sloth crying as it climbed down a little branch, Penny responded more to the sound from that video than from the one of a little kitten mewing at its owner's patio door. When I played the sloth video, Penny came right up to my laptop with wild eyes, as if I had some strange animal in my lap that was in trouble. Seeing how she responded to this, I played the kitty video and waiting for her to become even more alarmed. Instead, she simply walked to the patio door and proceeded to beg to be let out.
