I stopped adding at 10 when I ran out of names. I've named them after all of my past cats, starting with my childhood cat that I got in 1959 and continuing to the cat that disappeared in 2007. When either of my current cats comes into the room I say, A cat is here.
Looks like one of you cat lovers needs to start a "Got Kats" thread in the Android Central Lounge. Yer li'l pards are cute and all, but they're not really the Android 7.0 cats that the OP was asking about. Mister Whipple, here (and his 64 pals), is.
It's fine with me if people want to post pics of the real deal. We live on 20 acres and have a real herd of cats and that we care for. Can't figure out why, with all the real cats we have, I'm collecting another herd of virtual critters. At least the ones on my phone are cheaper to feed and the vet bills don't add up like the real ones!
