Hey, I am very against all this (use products that are not tested in any way if I can including ingredients) it has never occured to me they may test tea and food on animals. There is no logic behind doing that in my eyes :S NON at all... I'm glad I've never drank that tea though, but I found out the company that owns them owns pretty much 1/2 the supermarket stock!
You'd be amazed at all the things that are tested on animals. Is good that Lipton are stopping though. I don't use any products that are tested on animals or any that contain ingredients tested on animals.
