Rabbits love to grab and toss lightweight, unsecured bowls.
Provide a fresh, clean litterbox daily, adding hay on top of the litter as an additional enticement to use the box. Very limited plain rabbit pellets. Toys - plastic baby keys, empty toilet paper rolls, some hard plastic cat toys, metal canning jar rings, some parrot toys that hang from top of cage and other toys. Out of cage you can provide boxes filled with hay, cat tunnels, large PVC tubes or round cement forms to run through. Trim nails about once a month.
