Just out of curiosity, how sure are you that it is actually the mice you are allergic to? Everyone in North Carolina blamed all their spring allergies on the very prominent yellowish Pine pollen deposits on their cars. It has been studied and the pine pollen is too large, and it just happens to deposit when many other very allergic spring pollens were also released.
I was out biking around Durham long ago, and I noticed some beautiful yellow flowers. I stopped and gathered some for my wife and brought them home as a surprise. My surprise was that they were goldenrod, but I got credit for the thought!

There's nothing wrong with thinking
Except that it's lonesome work
