I switched to sand...turns out it is the chicks, themselves I am allergic to. Now that I know it, I will prob go back to the pine shavings, because sand is *stinky*.
Taking an Allegra + a Zyrtec and so far still have itchy eyes and runny nose. It'll be better when I move them from the mudroom to the garage. Already better than when I had them in the living room. I'm sure I'll be fine once they're outdoors forever, but gee whiz.
