The Tri-State Zoological Park was a 16-acre (6.5 ha) zoo located in Cumberland, Maryland, United States.

[2] In February, 2020, four years after beginning a legal battle, PETA forcibly removed three big cats from Tri-State Zoological Park to a facility in Colorado.

[1] The cause of the fire was ruled accidental due to older electrical wiring beneath the building, and the zoo and animal rescue has remained open.

[citation needed] In December 2019, a federal judge ruled that the park must relinquish possession of its large cats (two lions and a tiger) after the court found violations of the Endangered Species Act.

The judge's ruling described the deaths of two tigers in 2019, and cited "fetid and dystopic conditions" where "filth and feces dominate."
