On last night's Hoarders, clutter prevents a sick man from using a helpful breathing machine. He is suicidal about his home, which could soon be taken from him due to the mess, yet still says it's "not nasty."
Hoarding can be a very dangerous habit. It's filthy, unsanitary, and poses serious health threats. Although it's kind of hard to top the dangers of having so much stuff that you can't find your guns strewn throughout the house.
Two hoarders, Shirley and Bailey, tried to take in as many stray cats in the neighborhood as possible. In taking in around 76(!) cats, they overlooked one important thing: feeding them.
