What is in the toilet stays in the toilet

I have a problem. My kids leave the toilet seat up. My 14 month old Titus loves to play in the toilet. So far all types of things have been found floating toys, food, and my personal favorite dog food which when soggy resembles poop. This week though Titus took my sneakers and you guessed it gave them a bath in the toilet. Now I guess I could wash and wear them but it grossed me out so much that I threw them out. I mean really no one would notice but I would know and just feel gross. So needless to say I will be purchasing a new pair of shoes because what I find in the toilet stays there!
