We have a fairly small yard with a 6ft fence all the way around. We’re thinking about constructing a top around the top that is commonly seen online. It basically has the same design in various fashions from somewhat heavy gage plastic to bent wire types. Some are even commercially sold. Has anyone tried this? I’m thinking it’s a great idea for them to enjoy the outdoors with safety. Comments on your experience? Can’t really afford a catio due to my husband having cancer and all.
