The zoo's animal collection changes periodically with AZA recommendations regarding breeding through the Species Survival Plans (SSPs), animal deaths and births. The spring of 2013 proved to be a very fruitful time at the zoo as it welcomed two African lion cubs, six African penguin chicks, one golden lion tamarin baby, three domestic goat kids, a California sea lion pup and a Bornean orangutan baby. In 2018, Seneca Park Zoo began its multi-year Master Plan improvement. The first elements of a Cold Asia area opened next to the animal hospital in June, which included new habitats for snow leopards and red pandas. In September 2018, the zoo opened up a new African exhibit called Animals of the Savanna. The five-acre area includes Masai giraffes, plains zebras, a white rhino, naked mole rats, an aviary, and some other smaller exhibits.
