This is the view out the northern window in my bathroom. My neighbor has been cleaning their yard for years, which has just involved them piling garbage in a trailer. The trailer has never been emptied, and At this point I doubt they could move it without the majority of the trash falling out.
Luckily the fence on that side of the yard is 6 feet, so I do not really see the trash under normal circumstances.
It’s hilarious that the “too lazy to empty the trash bin” behavior can scale like this. Worst case for me is I pick up a couple things that fall when I empty it. For them… well as you said it doesn’t appear emptiable!
I was skeptical this cat shelf design would hold, but I picked one up and for the last year it’s been my cat’s favorite thing. Highly recommend them. Just make sure the suction cups aren’t warped, you put them in hot water, clean the window, follow all instructions etc.
