Have you given her any old (or new) hay? It could be the dust, Pie has been sneezing abit lately but when I took her to the vets (about stasis) I asked the vet and he said she was fine, might just be the time of year with all the dust, fur, pollen etc in the air?
If she's doing it alot and/or violently take her for a check up anyway just to be sure. :wave:
