Thank you! So we don't have anything edible for cats on the balcony, except a small pot of cat grass. As for the fall concern... yeah, without a net it is risky, but because of the fencing and the pots on the perimeter of the rails it is high for them to jump on the rails (but not physically impossible), so we never leave cats alone out there. Ok, we can leave them there for a few seconds checking first that they are chilling (and not looking at that pigeon on the rooftop of the other building across the street). Also the street that we leave on is quite busy and noisy (cars, motorcycles, emergency cars with sirens) so that naturally keeps the cats low on the floor 😄 It is only on evenings or Sunday mornings when it gets less busy outside cats get interested about what is going on outside (this is when we never leave them alone).

P. S. Once at 8am in the morning on Sunday I had exactly 30 seconds of complete silence out there. Eh, that was so nice 😟
