Holy shit you just uncovered a memory I’ve been repressing for a long time. When I was selling my house in Michigan around 2008 (just before the real estate crash) I had an offer on the house that was amazing. They did a walk through and loved it. We had two cats and a dog but I made sure to remove all evidence of pets before they arrived. We arranged for an inspector a few days later. On that day my plan was to go get the pets 30 minutes before their arrival. They show up at the house an hour early with my realtor and the inspector. When they go inside the wife sees my dog (in her crate) and absolutely loses her mind. Like screaming. My realtor calls me up frantic saying they want to withdraw their offer as nobody told them a dog had been living in the house and they felt entirely deceived. In the end I ended up paying for an extremely expensive professional cleaning service that sanitized the entire house. That was when I learned this TIL.
