I Survived in a Stranger's House

"I lived in a stranger's house for two years and this is what I found," says the author. "There was a 730 day period where I both lived and worked in the houses of total strangers." The writer has compiled a list of crazy things he encountered in strangers homes, either accidentally while cleaning or purposely while snooping. A goldfish on the stairs and a live goldfish. Could it be a cat that came in through maybe a window?
