No, way, you need to kill animals! f*** all those animal groups like PETA
-Postal 2. You can kill dogs, parade elephants and use cats rectums as silencers
-Carmageddon. The countryside courses have cows, they are fully killable. Carmageddon 2, dogs can be seen walking in the street, also killable
-Hunting games like cabelas, moose, squirrels, turkeys, bears, etc can be shot to a bloody mess
-fishing games. Well, you do fish fish and you eat them
-Half Life 2. Piegeons and ravens are killable, with full ragdoll too so you can see them hit the ground with a thump. Headcrabs, ant lions, etc are technically "animals"
-Hulk. Gamma dogs.
-Tomb Raider, lions are in jungle levels, have fun putting a hole through its skull
-King Kong, the dinosaurs jaws can be dislocated
-MMOs of all kind. There are usaully wildlife animals (like bears, boars, cows, etc) that you can train on
So if any stupid ass PETA group tries to blame GTA4 for the cause of animal creulty, they'd have to blame all these games too
