This might not be the sound you would expect to hear from one of the biggest cats in South America. But this adorable Jaguar cub is only just beginning to assert himself.
The Philadelphia Zoo introduced Lucha, a male Jaguar, born on June 3.
The feisty feline was filmed suckling on a finger before letting out a surprising baby roar that is likely to take more effect when he's older.
On the IUCN Red List, the Jaguar is listed as a near threatened species due to habitat loss and persecution.
