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.

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.
