A lot of people here, particularly those in the UK, really don't like CareFresh. Personally, I've never had a problem with it. I've used it for seven years, for everything from mice and rats to chinchillas and guinea pigs. I've never had an animal with an allergy, but and the dust has always been really minimal. The one time it had a weird scent to it was right around November, when all the packs in the store smelled strongly of pumpkins. :? These days, I use a store brand of the same kind of bedding, and I find it keeps the does smelling fresh for ages longer than wood or other paper beddings. The bucks I can't really tell with, since they always get less-than-full bedding changes and start to smell faintly within a few days.
