I get asked that all the time. Nothing seems strange to me anymore. I've worked in smack head houses, hoarders houses, all sorts.
A house stacked high with used sanitary towels.
Walked into a house and rats came running down the stairs to be fed. An old farmer had been feeding them dog biscuits, he slept sat up in a chair in the front room, feeding the rats like pets. One day he had a heart attack and the rats had eaten him. Honestly. We arrived after the body had been moved obviously.
