Building a Chicken Coop - Good idea! Bought a chicken coop, raised it up and added a floor. It opens into the house. The cats love it! Building a chicken coop does not have to be tricky nor does it have to set you back a ton of scratch.
Keeping the Litter Box Area Clean- rubber garage tiles from a home improvement store. The litter gets trapped in the holes, not tracked all over the house & works better than the mats sold in pet stores!
