To Deana Beek, et.al. Funny you should ask. Today my local vet did use the ear sensing thermometer set for the "rectal" calabration, and it took something like half a second! They said they made many comparisons to check for themselves, and it was fully accurate. That's all they use now. I think they said it works on ferrets, but not cats & dogs.. Don't know why. Maby some day I'll "invest" in such a marvel. Gary & the gang of fur The pure of heart carry within a source of good. [Posted in FML issue 1626]
