I voted that I hadn't thought about it, but have only closed the lids with kittens in the house, and that's been about 8 years ago. I close the lids for about 24 hours after cleaning them, just to get all the residual cleaner flushed out of them.
I live in the country and have caught my dogs drink out of puddles that would make me sick. The toilet water they love to drink is far better than the things they find outside.
I've only had 2 cats that liked to drink from the toilet bowl. It really doesn't bother me, but again, I've seen feral cats drink out of much worse.
Perhaps I'm not so squeamish anymore after living with pets for 50 years.
