Roberta Glazier of New Jersey shares an idea for keeping litter in the box. Her mini-lop with huge back feet could kick the litter all the way across the room. Her solution was to drill small holes in th bottom of a second litterbox with plenty of holes in the corners and not too small. Then the first litterbox was put inside the second.The urine could run through the holes to the litter below, but bunny could not get into the litter. This got bunny through the "teenage bunny months" before she was spayed. She no longer needs the second litterbox, Roberta reports. Other solutions to the litter digger problem is to make or purchase a wire rack that sits inside the litterbox or convert to the large hay tub.
