100! thats way too hot
95 tops is all i would ever go and up the humidity it will loosen the mucus.
what caused to original problem was more than just one mistake.
baytril isnt hard to find almost every vet has it and most vets should be able to figure out RI even if they are not herp vets.
as for the mites you better get some proventamite asap and i would use it on all your caging. i have never had mites yet i always have PAM on hand and use it monthly just in case.
