PetSafe Microchip Cat Door Tunnel Extension - For Thick Walls And Doors 5cm Each

So this PetSafe tunnel extension is exactly what you need if you're trying to install a microchip cat flap in a thicker wall or door. Each extension adds 5cm to the overall depth, and you can use multiple extensions together if you need even more length. The installation is tool-free and seriously simple - they just snap together with the existing PetSafe Microchip Cat Flap, and you can use glue for a more permanent, flush fit if desired. The tunnel design creates a longer, more comfortable entryway for your cat, which can be less intimidating than a short, abrupt opening. It's specifically designed for the PetSafe Microchip Cat Flap, so compatibility is guaranteed if you have that system. This is perfect for situations where your walls are thicker than standard door thickness, like in log cabins, brick walls, or specially constructed pet doors. The white color blends with most interiors, and the plastic construction is durable enough for regular use. Whether you're installing a new cat flap in an unconventional location or adapting an existing one to fit a different opening, this extension makes the installation possible without complicated modifications. It's one of those simple accessories that solves what could otherwise be a major installation headache.
