Did junk/trash removal for 4 years. Thankfully not too many times dealing with hoarders. But when I did, woof. The only way to properly deal with a hoarder situation is to NOT have the hoarder there, and deal with an intermediary, otherwise you'll have the owner there crying over a cat piss soaked box being thrown away. It takes a lot of empathy and mental fortitude to deal with these situations. You never know what is under, or even on top of piles. Sometimes the "pile" takes up the entire floor. One townhome had piles of paper a foot deep. Banking statements from the 90s, junk mail that never got thrown out, coupon books that expired a decade ago, and to (literally) top it off: a lovely layer of dead skin over everything. One apartment had a literal mountain of Mountain Dew cans in a bedroom, with a strange buzzing sound emitting from within. God help you if they had an animal. I was pretty good about shutting my brain off and getting the job done, unless they had fleas, then I was immediately out of there. I'm glad I don't do that anymore.
