... well, second to my Guitar Tuner app.
For years I have learned to adjust for my cats specially on work time. They are always on my desk either chasing my hand when I move my mouse or chasing the cursor on screen. So since this appeared to be their greatest form of high-tech entertainment (other than crumpled paper, paper towels, tissue boxes and plastic bags) why don't I just give them what they want and maybe, just maybe, they'll leave me alone. So there, I looked for a cat entertainment application in the itunes store and made my very first cat entertainment purchase - and by far, the cats are still crazy about it! I am crazy about it!
Paint For Cats, you are awesome!
The only problem now is they try to dig under the ipad to check if the mouse is hiding there.
