Kitties wander in through the flap. The bubble over each one shows what it wants. Make them happy and they head home. Tap the door to call another kitty.
Tap a kitty to pet it.
Muddy? Drag it into the tub.
Sleepy? Drag it onto the cushion.
Hungry? Open the fridge and drag a snack to the kitty. Every kitty has one yucky snack!
