Just recently, like within the past day or so, every time chico is done eating a treat, eating some food, or drinking some water, sometimes he will let out one little, light kinda cough. he doesn't do this any other time, just after eating and drinking. he is acting like his usual self, so i'm sure he's not sick or anything. he eats normally and drinks normally, its just that one little light cough he lets out, any ideas? do any of your chi's do this?
