I don't have allergies to my chin. But when it comes to the dust bath and changing their bedding, my nose and eyes start flowing like a faucet....I've combated (sp?) the dust bath with just simply putting a wet towel/ handkerchief over my nose and giving them a more enclosed area (like aquarium tank) to bathe in instead of leaving them in the open....as for changing their bedding, I really can't find a way to stop the allergies so I'm going to switch to fleece liners as soon as I run out of bedding =D
