According to a statement from the Houston Zoo, its Ankole cattle, named Luni Tune, passed away on Wednesday at the age of 23.
Zoo officials described Luni Tune, who was brought to the Houston Zoo in 2006 with his two brothers, as "the shy one with the perfectly symmetrical horns, [with] a way of making himself known."
As he got older, Luni Tune's team built a health plan around him, including joint supplements, a special diet, and the kind of steady, attentive care that comes from really knowing an animal, according to the Houston Zoo.
The Houston Zoo also said that Luni Tune was their last Ankole cattle, adding that "this place feels a little quieter without him."
