In mid-December 1965, Trout received a hippopotamus as a Christmas present. The hippo, named Hippie, was boarded at the
Louisiana Purchase Gardens and Zoo in
Monroe, Louisiana, until a hippo pen was completed eighteen months later. The present zoo was built around the hippo pen, and was officially opened on June 17, 1967. The zoo was named after Trout’s mother. Since 1989, the Lufkin Kiwanis Club has helped with projects at the zoo. To date, thirteen projects have been completed, totaling over 3,200 person hours of donated time and $35,000 of donated materials. Paddy the female southern white rhinoceros died at age twenty-eight on November 9, 2023. In April, the zoo lost its Association of Zoos & Aquariums accreditation. Bwana the male southern white rhinoceros permanently transferred to the
San Diego Zoo Safari Park to generously join a larger crash during that same month. Chitabe the male southern white rhinoceros arrived from
Lion Country Safari two years later. ==Animals==
