Earthbath as in Dog shampoo right? I probably would not use it dog shampoos tend to be a bit too intense for hedgehogs. Shampoos meant for cats though are usually safer. Also someone can correct me if I'm wrong but I'm pretty sure that Aloe is not safe for hedgehogs. At least not our Pet African ones. All of the earthbath shampoos that I know of either have scents or aloe so unless the hypo-allergenic one does not and also has oatmeal then stay away from them.
