This app works in a few ways. It shows video of people who not only care about animals, but give their lives for them. Its a reminder that there are still good people in the world. Another thing is you can watch videos of the big cats. Up close and extremely personal, which is still unique online. I also think when you use the app a tiny bit of money (from the ads) goes to help the animals. What more do you want? As a side note, I went to their site and bought two tee shirts that were really comfortable and, again help the foundation. Good app, great cause. Go for it.
