Allow your rabbit to hop freely through your home if it uses the cage only as a home base. If not, make sure your rabbit is in an area that is secured from other animals or potential escape. You can also put your rabbit in a different cage or your bathtub. Just make sure the drain is covered. Avoid letting your rabbit roam outside, which can expose it to harm from other animals.
Give your rabbit leafy greens or food pellets while you clean. Make sure it has a toy like an old phonebook or chew toy to satisfy natural urges to dig and chew.
