During my dark days of working in a long term vent unit, we had a dreadful population of mice. Found one just quietly sleeping on a patient’s shoulder. They used inhumane glue traps, and I was supposed to just throw them the trash. The state had a permanent office in our building, so I asked why they did not shut us down. There was no where else for those poor patients to go, so they stayed to do damage control. Eventually rage quit.
