I just flossed my teeth and I'm chewing on it for the minty freshness it provides... can I swallow floss? What will happen if I do? Cats shouldn't play with yarn or twine or string, because it can knot up their intestines... but what about us? My research tells me that cats don't have an appendix like we do. Our appendix seems to be the garbage catch-all. I've heard of people who have had their appendix removed and it was filled with lots of wood pulp from chewed toothpicks, or marbles, or things equally bizarre. Would the floss end up there, or would it just be safe? My intestines aren't nearly as small as a cat's intestines. Perhaps they would be safe. Despite the horror stories involving gum (all false by the way), I've always swallowed it. Sure I could find a trashcan, which is either tedious or impossible (and when I'm done with gum I want it gone now), or I could spit it out, which is inconsiderate. But it seems just as easy to swallow it. It's only going one way then. Gum's made of rubber, which seems to scare people. "You can't digest it!" But that's never stopped them from eating fiber or buying Metamucil. "It'll stay there for seven years!" Yep, pretty sure my stomach and intestines are lubricated with some sort of liquid... the next time you find gum sticking to water, just let me know and I'll cease my exuberant, devil-may-care gum swallowing. That is, unless it's staying in my appendix... but if that were so, I'd've had appendicitis long ago. The human body can only store so many pouches of Big League Chew. I'm pretty sure my intestines are all attached securely inside as well, because I've never had the problem of my stomach and intestines twisting around as a result of rolling around on my back, like a Horse with colic. Which is what would happen if it were to roll around on its back.
