Avoid Furniture Near Windows. Pets are going to climb on chairs, couches, and other things to see outside. You can train them not to get up on those things and that’s a great start. But to further protect your windows when those pets are really curious as to what’s going on outside, keep those furniture pieces away from the windows. If they climb on the couch, they can’t get to the window anyway. That will keep them safe from jumping into the window to get a bird. And it will protect your window as well. Learn more.
