Alright, my wife is deathly allergic to rats. She also has a tree allergy. Yesterday I was outside cleaning tubs, wife was watching not touching and went into a sneezing fit that later led to serious coughing and a near er visit. I think, even being outside, she got some rat aspen dust and small rat hair fibers breathed in. what other tour of bedding can I use to at least cut down on that that will last as long as aspen. Still getting her an epi pen.
