Our state news on Tv, which has a strong history of getting scientific, medical, and statistical reports wrong just had a teaser about weather perhaps affecting rates of uroliths. Ferrets, of course, get uroliths, with three types most likely. It makes sense that weather could play a part since aspects like heat and drought might alter the amounts of dissolved minerals in water, with well water probably being more variable than many public sources, while insufficient hydration is a greater risk with high temps and drought. Online I found: http://www.ncbi.nlm.nih.gov/pubmed/23869912 Whether there has been a new study released I do not yet know. So, keep those ferrets hydrated enough in summer heat and drought to decrease the chances of yet another medical problem which can be related to poor hydration, heat, or climate changes.
