Elbroch (2003) describes badger scat as rancorous (can confirm); assume fart

molluscs don't fart- would like to question inking as farting in extant cephs

Black Spinytail Iguana

Seems to occur more frequently when less insect/animal protein is consumed and higher quantities of fruit/fiber are eaten

Equus quagga burchellii

Often silent but deadly. Thick, and...meaty? If it were a color it would be brownish-yellow.

Periplaneta americana

Trachypithecus, Colobus etc.

Agkistrodon contortrix

Elicits a small squeak, so small that you think you may be mistaken...until it hits you. Very dry and feral, with a slight hint of stale Copperhead musk.

Domestic hedgehogs

Canis lupus familiaris

but often takes blame from nearby hominid, Boston Terriers are famous for their farting; known to scare selves with their farts

Pyxicephalus adspersus and Ceratophrys sp frogs both can and do fat quite often and rather pungently. (Frogs have weak sphincters, unconfimed if audible)

Corellophus ciliatus

Urocyon cinereoargenteus

personal observations of captive Green Iguana

Several examples heard every day, very audible and stinks to high heaven

Isopods (marine and terrestrial)

Cirolana harfordi,Porcellio scaber and Idotea resecata

fav joke here "what's invisible, floats through the air, and smells like bunnies?"

wide variety, see attached paper

Yes, of the silent but deadly variety (methane AND hydrogen sulfide!)

My friend's parakeet farted in my face when I was 9 years old. (Note: literature disputes this - see "Birds", which are purported not to fart)

Ingest air with solids during summer months. Associated with behavioral changes until release of gas

Gas is dangerous in rabbits, however. It can cause intestinal stasis and lead to death within a short period of time.

"Sounds wet". Increased frequency with higher fruit and/or fiber intake. High parasites loads also lead to an increase in flatulence.

Probably not, but if they can they'd be tiny. No one to offend if you're asexual tho

We have not heard any audible sounds from the vent in 5+ years of care

Snakes - corn and rat snakes
