Why do dog and cat farts smell so bad?A carnivore's protein-rich diet produces relatively small amounts of intensely stinky gas because proteins contain lots of sulfur. A dog's or cat's farts are rarely audible,but the odor is overwhelming. I have asked biologists why dogs and cats generally fart silently, and their theories include 1) the amount of gas produced is small, but potent, (2) the horizontal orientation of their gastro intestinal system puts less pressure on the anal opening, so the gas is expelled more slowly, (3) their anal sphincters don't close as tightly as humans' because it takes less force to hold in the contents of the colon -- again because of the horizontal orientation of the gastro intestinal system -- and a loose anus makes less sound, and,my favorite (4) dogs and cats don't feel embarrassed about farting, sotheir sphincters are more relaxed, leading to less noisy flatulence.
