About Catio Designer
Design a catio in 3D for your own space and get the full material list
Catio Designer is a side project for cat owners who want to build an outdoor enclosure that fits their own home. You choose a window box, a lean-to, a freestanding run or a balcony screen-in, enter your measurements, and the catio is framed in 3D from standard lumber. It checks mesh, gaps, roof slope, shelf steps, space per cat and shade at your latitude, each with a source, and lists every board, mesh roll and screw to buy. The design lives in the share link; nothing is stored on a server. The designer is free. Pro is 19 USD once for a cut list with diagrams, a mesh layout, a build plan PDF, add-ons and GLB or OBJ export.
