A lion at a zoo in the Netherlands has been given a vasectomy after he fathered five cubs last year.

The 11-year-old lion, named Thor, impregnated two lionesses. The first gave birth to twins, while the second had triplets.

"Why are we doing it? Because he's a proven breeder," the chief vet at the Royal Burgers' Zoo in Arnhem said.
