I have a 4 month old Siamese kitten who farts a lot. I dont know if this is natural but man it stinks. 7 out of 10 times that I pet him he release this fart that stinks so bad you can taste it hahaha. I don't know whats wrong with him. I think its that Kitten Whiskas he keeps nibbling on. Ill try to post some pics of him later.
