I am allergic too, altho mine affects my asthma and early stage COPD. I can no longer clean their areas and have to leave that to my husband. I am still undecided if its the actual animal, because I can handle them without issue , so maybe its some type of dander build up in their basking areas, something in the urates or even from food particles that dry up and become brittle quickly under their lights.
Whatever the cause I dont clean up after them anymore . We do have geckos, a beardie and a uromastyx which seem to give me no issue at all..
