here is what professional mice and rat breeders recommend aspen, pellet bedding(other then pine), unscented for any and all types of bedding. that stuff made from paper or carboard not sure which it is made of. some even listed kitty liter as a substrate (actually recommended most and if nothing else line bottom of cage with the litter

Raptor my mom also has asthma and has issues if the mouse cages stink i use aspen and any time she visits she aint had any issues with the smell and i go a month with-out changing bedding but i do put a Lil bit of kitty litter in bottom of the cages first
Feeder mice aren't going to live long enough to get health issues. So that's not a problem. Aspen shavings are also as bad as pine when it comes to ammonia build up. The paper .stuff you're talking about is the absolute worst. It's very dusty and goes bad very, very quickly. It's also very expensive.
