Animal testing is not required by law.  It is a industry standard.  It is important to understand the difference between these two symbols:

1.  

and

2.  

—-

1.  This symbol tells the consumer that this product is not tested on animals.  And that is it exactly.  It is important to understand that this means the product was not tested on animals, but the individual ingredients COULD have been.

2.  This is the leapingbunny.org symbol (the symbol which the blog is named after) created by the Coalition for Consumer Information on Cosmetics (CCIC) in 1996.  CCIC is a crew of several different parties working together to make a new industry standard.  The symbol means that the product is 100% cruelty free, including ingredients.  

In short, there are many different ‘bunny’ symbols out on the consumer market today that may confuse you.  Making a conscious decision to look for the second symbol will ensure that you are using products that did not harm, or cause suffering towards any animal.
