Izzy the cat’s favorite litter box is the one outside in her catio. When it rains, the litter gets wet (yuck), so awhile ago I put an old cookie sheet over the entrance and secured with with duck tape. It wasn’t elegant, but it worked, until the duct tape failed. Hm. I don’t know why I didn’t think of the scraps of metal roofing by the chicken coop then, but I did remember this time. A couple screws to attach the corrugated metal to the frame, tin snips to round the corners to reduce risk of injury, and tada, a outdoor resistant rain roof for the litter box. Faster and easier than duct tape. Please forgive the dirt, it will wash away with the next rain and it has been a very busy week.
