This is playful interaction between a mother and her sub adult leopard cub.
This male cub is already bigger than his mother but she still hunts and provides for him.... sort of like a 30yr old bachelor living with his parents.
In this image she has made a kill and gone to fetch the 'youngster'. He is so excited about this that he jumps all around her with excitement and anticipation.
Already we can see the instinct to wean the cub off its dependance kicking in as she growls at him while he takes a swipe at her.
