a rental toilet has a dark clay looking stain in the bottom of a toilet that the renter was unable to remove. At first I thought it was very hard water, however, there was no evidence of stains in a second bathroom or any other fixture. There is evidence of cat litter in the area and I was wondering if cat litter could form a tough clay layer in the bowl? Also, if cat litter is in the toilet, could it be in the drain piping and be a problem waiting in thwings. Can anyone suggest a way of removing from the bowl?

My mother had a cat and dumped the cat liter down the toilet. At 90+,She would sometimes forget to flush the stuff and it would cake like that. When I would find it I would use a stick to dislodge what I could, and After much use it would dissolve and be gone.
