Objects never fall on the floor after N nudges in which N belongs to the set 2 + 3x, where x is a integer greater or equal to zero.

It’s common cat knowledge.

That is what causes a greeble overflow error

While thing.location != The floor; do nudge(4)

If it’s anything like my cat, it just moves onto the next object offending her by being on the table.

Nah, that’s still nudging. Your cat just chooses to make it more interesting by not using her peets every time.
