Do rabbits fart?
However, rabbits usually have a low-fiber diet, which is high in carbohydrates. This can lead to a gas build up (Known as GI stasis). So, rabbits do not only fart – but they have to do it in order to avoid a gas build up, which can be deadly to them if not treated on time.
Do turtles fart?

Do dogs fart?

Do plants fart?
If you define fart as the Merriam-Webster dictionary does—to expel intestinal gas from the anus—then no, plants don't fart, because they don't have anuses. However, they do expel gas (including methane, a greenhouse gas found in human and animal farts), so they basically fart in their own plantlike way.
