Also, it's a truth universally self evident that poop stinks. "Poop still stinks and you still need to clean the 'litter box,' aka toilet bowl," Bays said.
Dr. Barrack agreed: "Unfortunately, cats can't be taught to flush so the smell will remain, and eliminating odor is what most people assume will be the result of teaching cats to use a toilet."
But more seriously, cutting the litter box out of your cat's life could have a backlash. "Denying your cat the ability to be a cat can cause other behavioral issues," Bays said. And Dr. Barrack pointed out that cats can be territorial. "This can be a problem if there is one toilet in the household," Dr. Barrack added.
