What Does a Slow Spret Smell Like?

Most animals do fart. Sloths don't fight because their digestion is so slow, like all the rest of them. It take them so long to work through the farting process that the gases would build up inside them and woud become poisonous. So instead, they are reabsorbed through their intestines into their blood streams,. Then those gases are taken up to their lungs and they breathe them out instead. I desperatelywant to know what a slow spret smells like. The early morning used to be called sparrow fart - but think about that. Sparrows don't fartno. Is that true of all birds? All birds don’t fart? Or no birds fart?!
