Net Cage on Balcony for Cats Without Drilling Holes

When I do bike training I like to ride indoor, but it can get too hot. Recently, it has become more problem because I can't open the door to the balcony because of cats. I decided to make the balcony into a huge cage. But the challenge was to do it without drilling holes on the wall or balcony. I used cheap poles from Amazon because they looked big and strong, but it didn't work... BOY Katzennetze https://www.boy-katzennetze.de/ My training data is here.
