My wife's pig has recently taken to peeing on the floor instead of in her litter box. She's a little over a year old and has been good at using the box since we got her. We have her confined to the laundry room during the night and while we are at work which is about 10 ft square, so it's not a big area. We empty her box every time she goes in it, but leave the newspaper in the bottom so it still smells like her box. We started cleaning up the floor and spraying an odor eliminator on it, then putting corn around hoping she would associate the floor with an eating surface and not her bathroom, but it hasn't helped. Any suggestions would be greatly appreciated.
