I’m a bachelor. I live alone. My toilet gets configured exactly as I say it does.

When not in use or being cleaned, the seat and lid are closed. Because I’d expect Izzy to fall into the toilet then go scampering around getting toilet water on literally everything, only to go to the litter box, get shit grit stuck to her wet fur and track THAT all over the house…

Cat proof toilet: close lid. That is an order.
