Hi Koala,
I didn't see that you had replied as it went on to page 2.
My plants are on my balcony but I live on the main floor so my balcony is only about 1 1/2 feet above the ground. I've seen squirrels jump up here and a few times during the winter I saw one digging in a plant pot to hide its peanuts there.
I've seen raccoons around my building but not on my balcony.
