Caturday: Get a new cat every minute on your iPhone or iPad... The light-hearted app delivers you a new cat photo every minute of the day. There are four different cat channels, so you can hop from channel to channel to see different cats. They pull cat pictures from Creative Commons sources with new photos added every day. Cat-a-minute! is free from the iOS App Store. Two 99-cent in-app-purchases let you add on a dog pack, or a speed pack that displays new images every 15 or 30 seconds.
