Floofathon (floofinition) – a housepet’s race around the house, usually on an erratic course, and often at bewilderingly high speeds, typically lasting for several minutes, and usually with uncertain origins or causes; something (such as an event, activity, or session) characterized by a housepet’s great concentrated effort.

In use: “In an impressive floofathon that lasted over an hour, the four cats gathered at the window and watched the noisy little sparrows at the bird feeder.”
