I must admit that some of the most fun I have with my iPhone also requires a cat. Or three. Yes, I have no fewer than four apps that meow and make other cat sounds. That sounds a bit weird, but if you're a cat owner (or a cat owns you), there's lots of fun to be had with such apps. See, cats may think they're really smart, but in reality few cats understand how an iPhone works. So if there are meow sounds and there are no other cats around, that is certain to raise a few whiskers.
