Suggestions for cat-proofing a highrise balcony?

I’m looking to allow my cat to roam on the balcony without risking any number of his nine lives. Ideally I’d like to make a roller shade made of mesh or a shower style mesh curtain, but this would be more expensive and I’m not sure I’d be willing to go up on a ladder 10’ high on a 27th floor balcony to install it.

Since I am only renting I thought it would be best to buy some mesh fabric and mount it to the glass with suction cups or velcro. This way the tarp would be removable should I want to walk around on the balcony. Are there suction cups that would be sturdy enough outdoors? I’d appreciate any and all suggestions on mounting solutions, mesh material, examples on the market, or anything else I haven’t considered. Thank you!
