it seems like my guinea pigs might be allergic to Timothy hay. Not sure about it though but it looks like it. Also, they're sneezing. Sometimes thrice in a row but there is no other symptom at all. No discharge, no weight loss, or anything at all. Only loud sneezing. The sneezing started a few days back and no matter what I do, it isn't going away. The vet has asked me to wait and watch due to lack of any symptoms. Can you please guide me what to do? I'm really worried. Thank you in advance
