  • There are 3 key things you should keep in mind when selecting the right pet door:

    Install location: The answer is 'anywhere you can put a hole in the house'. You can cut a hole in a door,wall or open a window or sliding glass door. You can even install (with help) directly through any glass. Remember to consider the possibility of a future uninstall because while a window can be closed but a hole through brick can be difficult to repair.

    Buy the right size: See 'Measuring your Pet' to save money as people usually overestimate the size required. If your pet will be using their dog or cat door their entire life they may need more clearance, especially vertically when they're older.

    Consider climate including wind: Some pet doors will blow open easily, some don't insulate and some don't seal. Consider the pet door you're interested in according to these three energy-transfer issues before you buy!
