A year ago we built an amazing catio, run, and nest for a feral mother cat named Mama on behalf of a kindhearted couple who had rescued her kittens. Now we added a 3-part addition for the kittens which includes a catio tower, run, and nest on the other side of the house. The best part is that the two sets of enclosures meet in the middle where we installed two dividers — one mesh and one plywood. The concept is that the cats can be completely separated, separated only by mesh, or left open creating a ginormous 6-prong catio for everyone to share!!! The idea is to reintroduce the now grown kittens to their mother slowly over time, recreating the family. It’s a beautiful thing!
