He protected two baby kittens against 5 other adult cats
"I watched this beautiful boy (Ghost) hiss at a bunch of other old cats to protect these two small kittens as the other cats were getting nearly aggressive towards the kittens. After letting everyone know that if anyone as much as curl a hair on their precious fur. He WILL mess them up. He proceeded to comfort and groom the kittens. He appears to have adopted the kittens as his own despite being neutered and unrelated."
