Kazi, a 2-year-old giraffe who lived at the Denver Zoo, died Tuesday.

The zoo said Wednesday that Kazi died after he was castrated. The zoo said castration is a common procedure that decreases a male giraffe’s competitive, aggressive nature and allows males to peacefully live together.

The zoo said Dobby — another male giraffe at the zoo — had been castrated, and castrating Kazi would allow the two to coexist.
