A camera in the lion's den at Scotland's Edinburgh Zoo caught a cute family moment.
This is mama lion Roberta. She gave birth to a litter of cubs at the Royal Zoological Society of at the zoo in June.
She and her mate Jayendra are a closely bonded pair raising their three cubs together.
Watch mama here: She's busy keeping her eye on the cub across the room, but check out the little guy sneaking up behind her then landing a nip on her backside.
Mama takes the shenanigans in stride.
The family are endangered Asiatic lions. They used to exist across southwest Asia but are now only found in India.
