PHILADELPHIA – An African lion is considered as the oldest held in an American zoo has euthanized.
The Philadelphia Zoo, says the 25-year-old big cat with the name Zenda recently experienced a severe decline in mobility and behavior. She was killed Thursday.

Zenda was born at the Johannesburg Zoo in South Africa in 1991. They arrived in Philadelphia two years later, together with three other lions.
The pride relocated temporarily to the Columbus Zoo in 2004, to return to Philadelphia for the opening of the Big Cat Falls exhibit in 2006.
