11 Best Cat Proof Window Grill: Mesh grills and invisible grilles

Being a responsible cat owner means that your cats must be kept safely indoors without the risk of them escaping or falling out from any windows, gates, service yards or balconies - but that doesn’t mean that they should miss out on the sights and wonders of the outside world.

My male kitty, especially, loves to climb up on our work and dining tables, as well as the kitchen countertop situated by windows, just to be able to look out of the window and enjoy the scenery or watch for birds flying around.

To ensure his safety, we looked into cat-proof window grilles and meshes so we wouldn’t have to worry about him whenever he hangs out by the window.

If you’re similarly looking around for cat-proof window grills, take note that the gaps between the grilles should be no wider than 2 inches, and if you have a smaller-than-average cat or kitten, the gaps should be narrower. This ensures that they can’t get through the gaps, and the grilles must also be strong and secure so that they don’t give way easily.

There are different types of cat-proofing grilles and meshes on the market too, and here are some of the best ones we’ve found supported by good reviews so that you can create a safe environment for your kitties. Note: Most prices are only available upon request based on your selected type of grilles, size and number of windows.
