My favorite bug in catOS is when an interrupt is thrown during the groom routine more than half the time the tongue doesn't get retracted. All cats do that, I've seen lions do it.
That happens regularly whenever the bones start to solidify. It's analogous to the "strech" function on other platforms, but functions significantly differently.
