Hmmm...sea monkeys. 'Cause cats, at least mine, require butt-cleaning, feeding, greeding, and feather-playing on a rather distressingly regular basis. I always think of kids as cats times two hundred. I don't know if I'll be able to handle it all without losing my (fragile) cool, but I know enough to plan not to have anything pressing to do (like renovate a house, finish my PhD) at the same time. Hopefully.
