I found info about Science Diet very easily on their site - including contact info and a mail address - even tho it is a P.O Box, but also an 800 number and an email page. http://www.hillspet.com/hillspet/contactUs/contactUs.hjsp And I am sure a vet's office would have their real address as well as they usually carry the quite a few of the Science Diet products. Just my 2 cents. Seems like a good company to me. Dawn, Socrates, Romeo, Simon and Alexander [Posted in FML 6042]
