I have a 26 feet long iron gate/fence in my house and I installed nets all over it so my cats would escape (which she still tried to do every night) and torture birds and bugs. Basically I live in an enclosure. Also because I love them I don’t want them to get hurt or ran over. There are some trees that (they don’t climb) and a patch of grass inside the gate but the birds learned not to go down here. Only once I found a dead bird…but roaches… oh boy
