[13][14] Animals which remained in captivity continued to be taken care of by zoo employees and volunteers despite the closure.

[22] Principal animals include a White Siberian Tiger named Kois, an anagram of former Manila Mayor Isko Moreno's nickname.

[24][25] It also formerly housed a lone Asian female elephant named Ma'ali (Vishwama'ali), which died in November 2023.

Due to her living in isolation for several decades, she had been the subject of various campaigns to have her relocated to a sanctuary overseas, but remained a major attraction at the zoo.

[27] The zoo's animal collection is divided into four categories: mammals, birds, reptiles, and aquatic life.

The Wildlife Rescue Center has been the subject of public scrutiny in regard to their animal welfare standards.

The area featured a butterfly sanctuary, a hanging bridge, a flamingo pond, a barn for events, and a petting zoo upon its opening on June 23, 2000.
