Ginger tabby in Turkey nurses parentless bunny

Osmaniye, Turkey:  A domestic cat named 'Sarikiz' is seen nursing an abandoned bunny. A lone rabbit was found in a field by Sarikiz's owner and brought home and they began feeding it. The ginger tabby domestic cat, Sarikiz, which had recently given birth to kittens welcomed the abandoned bunny and decided to breast-feed the little creature along with her litter.

It is not uncommon for a mother cat to breast feed another species of animal. It is cute though. It is generous and kind. You wonder what goes through the mind of cats when they do this. Do they know that they are being kind and generous? Is it merely an instinctive act as if she is programmed to let a bunny suckle at her breast? 

She must recognise that the bunny is not a kitten. It seems that there is altruism in the animal world.
