This is probably the easiest way to make an impact on cruel animal practices. There are amazing products out there you can use every day from companies that don't conduct cruel testing on animals.
PETA has a huge catalogue along with Leaping Bunny. I have the Leaping Bunny app which helps me identify good companies to give my money to and always look for the little bunny symbol on the back.
Walk through your home and take a look at the soaps, shampoos, detergents, etc. See how many already have that little bunny and how many don't. You may be surprised.
Take a look at the products I love. I have them broken down to Household and Beauty. Its a small change for you that will give back life to another living creature.
