I had kittens and their momma at home once. A little kitten hurt itself and it seemed to be dying. Since it was hurt so bad the others did not dare go towards it. Only the momma tried feeding it, offering her belly. But the kitten could not.

When they realized that the momma laid close and watched. Only it's brother laid down with him and stayed with him.

Funny enough the next morning the little kitten was alive and even begged for food. He started walking again slowly and survived the whole thing.

So in a way they seemed to care for their pack by making sure they did not hurt him further.

While he was healing the next week they never dared play with him roughly.
