Kiwi

Along with mutations, zombies soon emerged from the nuclear fallout. Kiwi was a cat who was chained to a pole by his masters before they evacuated, and had no choice but to be infected by the zombie animals. However, he is actually smarter than his zombie companions. Due to more strength when he got bitten he was able to break out of his chains and now roams free. He never wants to eat anyone, but because of his zombie cravings he has no choice.

 Kiwi is a cat who just goes with the flow, he never complains. He is pretty shy and just stays with his pack. He has also fell in love with a dog who survived the Apocalypse and is just trying to survive.
