Ferrets are usually most active in the early morning and evening.
They get into everything; they attack household plants, steal socks, and push things down from shelves.
They will steal items they treasure and hoard them in several stashes around your home.
They like to burrow into the backs of sofas, undersides of mattresses, pillow cases, drawers, ducts, boxes, and cabinets, and slip into very small spaces: wherever their heads will fit, their bodies will easily follow.
