STORY: The ZSL London Zoo's asiatic lioness Arya was seen curiously sniffing and scratching on the heart while male lion Bhanu could be seen keeping more of a distance.
The heart was handmade by zookeepers and scented with ginger and cardamom - the lions' favorite spices - as a sensory treat.
According to the Zoological Society of London (ZSL), the pair of asiatic lions are among the rarest and largest cats. Asiatic lions survive in the wild in only one forest in India.
The display comes ahead of London's annual pride parade on Saturday, July 2.
