I found a online list of companies that test on animals but it's hardly all inclusive, it includes post it notes and scotch tape and most likely any other brand of tape will be tested on animals too. guess the glue part they make them eat and or put on the skin and watch for reactions. So if you don't believe in animal testing you can't use any adhesives like tape or post it notes.
