Where's the cat?!?!

Emma has discovered my parent's elusive kitty cat, Puff (she came pre-named). Every once in a while we'll be sitting around enjoying each other's company and we'll see a very quick flash of grey followed by black.  Luckily, Emma isn't quite as fast as Puff. Emma chases Puff all around the house. This all ends with Puff running into the basement (where her litter box is) to escape into her kitty door and then loud barking commences.  Emma tries very, very hard to fit her body through the door to no avail. Puff will be very happy when the puppy goes back to Savannah.
