Hello everyone. I have been reading this group since I got my 2 guinea pigs. I just decided to make an account here because I’m desperate to save my piggy. As weird as it sounds, he’s allergic to hay! Timothy, Orchard, Meadow and whatever mix. It took me awhile to figure out, at first I thought he’s only having issues because of the dust. I use to vacuum clean the hay, there is no dust anymore. Anyway, the doctor agreed with me, he’s allergic to hay. My doctor said to get lucerne hay because he might not be allergic to that. Now I know it should not be feeded to adult g pigs. I have been thinking about green oats, is it a better replacement? But all I can find in my country is not that long fibre so it might not be well for his teeth. I'm looking for your advices, what shall I feed him? He’s also having an enlarged heart that produces liquid while he’s getting contact with something he’s allergic at.
