During my my almost 25 years of servicing homes, I have only on one occasion found 1 rat in a toilet. But a guy in England has invented a flapper device to help keep them out. “MultiFlap helps special needs teacher left terrified by rat in her toilet”
To be honest I’m not exactly sure how it got there, 2nd story shared bathroom. That would have been one big climb, to get to a toilet 20 feet up but I suppose anything is possible. Here is the link to that device http://www.multiflap.com – I think the one to fit US toilets is MultiFlap 2 (MF-2)
