Hi, my guinea pig has been coughing alot after giving pellets recently. I fed pellets and came back into the room and she was choking for a minute. I use a snuffle mat because she is a very fast eater but she has been coughing a ton for the past 5 minutes. Is it from eating or something else. She had a uri about 5 months ago but was treated and the coughing hasn’t started until yesterday. usually when she eats it will be like one small cough but these sound bad.
