Hi guys, does anyone have experience making cat-friendly spaces? My new apartment has a big gorgeous terrace, but it's very high up and I am afraid my kittens are going to take a tumble off the side. Because of the dog I live with, the door to the terrace will have to be open pretty much all the time so I want to make sure I have some serious measures in place to keep them safe going in and out. Anyone have an idea?
