Porch4Pets is an online-only brand focused on helping indoor pets experience the outdoors safely. Its main product is a window-mounted outdoor enclosure designed for vertically opening, single- or double-hung windows measuring 24 to 32 inches wide; the window must open at least 20 inches. The enclosure is intended to let cats move between the home and a protected outdoor space, and it supports up to 15 kilograms. It is designed for quick installation, can be customized, and folds away for winter storage. Replacement parts are available, allowing worn components to be maintained without replacing the entire product.

Porch4Pets offers Basic and Deluxe versions. The Deluxe model includes a removable indoor shelf, while the Basic model can be upgraded with one. Optional features described include an air barrier, canopy, and gap filler. The product is intended primarily for fair weather, though it can withstand accidental exposure to rain. Porch4Pets aims to make the product affordable, durable, and environmentally considerate.
