WATCH | Thor the lion has vasectomy after siring five cubs in a year 12 March 2021 - 10:08 By Reuters
A lion had a vasectomy on Thursday after his Dutch keepers decided he had sired enough cubs.
Thor, 11-years-old, had fathered five cubs with two lionesses in the past year, staff at Burgers Zoo in Arnhem said.
Veterinarian Henk Luten said it was the first time in his 35-year career at the zoo that he had carried out the procedure on a lion.
“Why are we doing it? Because he s a proven breeder. We have a lot of offspring and we don t want to have him overpopulating the genetic pool,” Luten said.
