Peace of mind
Having adopted two very active young adult indoor cats, we were scared that they could escape our get hurt in our upstairs windows. With the hot summer we've had, keeping the windows closed wasn't an option. The fencing has been great. We couldn't use screws on our windows, but the recommended heavy duty double sided foam tape has stuck them up with no problem. They cover all the gaps we were concerned about, and are very reasonably priced.
