The Science of Cats

This makes me feel sad.

I agree with bismuth83. That's why I can't watch those hoarding shows on tv.

I wonder if this could also be applied to people who are just a little bit untidy (lets take for example a desk) but seemingly can place their hands on something in that mess instantaneously?

My mother-in-law is a hoarder. She's not as bad as she used to be, but it was HORRIBLE for a while. She was not a 'clean' hoarder and would let her pets poo and pee everywhere on everything. You could smell her house standing half a football field away... and I am not exaggerating.
Thankfully her father moved back in to the home and basically forced his almost 60yo child to clean up the house.
It's infuriating trying to deal with all of the mess, but she's not a bad person. Just stubborn and in denial.
