Dog foods that test on animals

We've talked about Iams and a few of the non-food companies, but I have a list here of the food companies that test on animals.

IAMS, Eukanuba, Alpo, Arthur's,
Bakers Complete, Bonio, Bonus, Bounce,
Brekkies, Cesar, Chappie, Choice,
Choosy, Chunky, Felix, Friskies/Winalo,
Go-Cat, Go-Dog, Gourmet, Hills Science Diet,
Katkins, Kitekat, Mighty Dog, Omega Complete,
Pal, Pedigree, Ralston Purina, Sheba,
Spillers, Whiskas.

Ooops, the title should be dog AND cat foods that test. :) Sorry 'bout that.

But can we find out what kind of testing? I mean, are they doing nasty cruel stuff or just some focus groups:)

Seriously, though. I would expect them to test on animals. It is animal food, you know. I would just want to understand what kind of testing it is to make sure it isn't cruel.
