I understand wanting to save money. That doesn't mean free license to do wierd things. Here's the concept. Save on kitty litter by toilet training you cat (

LINK). That's wierd, not frugal.

Forget to leave the lid up? Not a pretty site when you return from work. Boss is over for BBQ and has to wait in line behind the cat to use the toilet? Bye-bye promotion. There are enough household squables between husband and wife regarding toilet etiquette without bringing kitty into the scene.

Don't want to pay for cat litter? Open the door and let your cat outside.
