My old boy Rafa was constantly getting into trouble; playing with snakes and getting stuck on other people's balconies were his favourite hobbies. He was a very gregarious cat and saw no problem with sauntering into other homes and making himself comfortable - I would often receive photos from neighbours (thankfully all cat-lovers) of him all comfy on their bed/favourite chair 
Kloppy is even worse, literally no sense of boundaries - he just assumes that everyone loves him. He's always on the look out for his next challenge, I can see his little brain ticking over. He got trapped in my neighbour's studio for 24 hours a few months ago and yesterday morning went balcony-surfing at 7.30am as I was about to leave for work
He was outside, unscathed when I got home at 5pm so he either jumped off a two-storey balcony or a neighbour found him in her house and turfed him out
