God's creatures

Why do we abuse animals? what have they done to us? I hear a lot of christians revelling in the fact that they stone dogs, step on snails and throw cats on the walls, etc. and it disgusts me. Do we not realize we are stewards of God's creatures? We need to take stock of ourselves as we cannot say one thing and act contradictory. Christians, please realize animals have feelings too. They have the Spirit in them too. We have dominion over them but that doesn't give us license to abuse them. Think about it please.
