I once had a friend who cared for around 20 cats. She wouldn't let them inside, though. They lived in a big shed outside her house. Her catfood bill must have been alarming. She finally rounded them all up - not sure how - and got them all spayed or neutered. Happy ever after.
I think, among other obvious problems, hoarders have no boundaries. They just can't say "no" to yet another animal. It puzzles me that these people think they're doing the creatures any favor by keeping them under such conditions. Part of the pathology, I suppose.
