PETA is known to be a type of organization that is focused on improving the welfare of animals. This is meant to help protect animals from the unfair treatment of some people. For example, the killing of different animals for fur has always been condemned by PETA. This is also the same as hurting other animals or not taking care of them properly.
PETA2, on the other hand, also follows the same beliefs that PETA follows. The main difference is that this is directed more towards the younger market. The aim of this is to help the youth understand that animals should be taken care of too as much as humans should be cared for.
