Do cats and dogs always pass silent flatus?

Cats and dogs, just like humans, can pass gas that is both silent and loud. The sound of their flatulence depends on factors like:

* The amount of gas: More gas usually equals a louder sound.

* The speed of the gas release: Faster release leads to a louder noise.

* The composition of the gas: Different types of gas produce different sounds.

* The anatomy of their digestive tract: The shape and size of the intestines can influence the sound.

So, while it's a common misconception that they always pass silent gas, it's not necessarily true. They can be just as gassy as we are, and sometimes, those toots can be quite loud!
