do you really think that the people who get the parasite are knowingly eating pieces of cat feces?

No, I think they are eating undercooked meat. Remember, a cat can only spread it for about two weeks. The people who do get it from cats are most likely not washing their hands after cleaning the litter box. That is eating feces, just indirectly. I do not do that, I wash my hands.

Or petting a cat. Or allowing a cat into their bed. Or sleeping on a couch that an infections cat has climbed onto. Or the cat walks across the dinner table or kitchen counter.

You seem to have a really wrong mental model of how fecal-oral transmission happens.

If I have Norwalk (Norovirus) someone else doesn't need to literally lick my butt or eat my feces to get it. If I wandered around their apartment naked (interesting image) and sat on or walked across random pieces of furniture, they'd be very likely to get it.

You are seriously overestimating the likelihood of transfer via those methods. The odds are actually very small. Simply having a cat walking around gives you very poor odds of transmission. It is not a cold.

Do you touch the faucet handle with your hands and then touch it again when you are done washing?
