Topeka ? Officials at the Topeka Zoo are discussing increased security options after vandalism led to the escape of a bobcat and porcupine last week.

Director Mike Coker said animal keepers discovered the bobcat named Johnson roaming the facilities and the North American porcupine named Prickles resting in a tree near its exhibit before the zoo opened Thursday morning.

Within two hours, the animals had been captured, checked out by the zoo’s veterinarian and returned to their exhibits. The zoo has only one porcupine and one bobcat.

“There was no injuries to the animals, no injuries to anyone at all,” Coker said, adding that Johnson and Prickles are “both doing great.”

An investigation revealed that a chain on a small, exterior access gate was cut, as were the lock hasps on the two exhibits. A Topeka Police Department report said the damage totaled less than $100.

Coker suspects the vandalism occurred late at night and that the animals weren’t out very long because they were near their exhibits.

The zoo has systems to monitor animal activity but not in the bobcat and porcupine areas.

“Quite honestly, it’s very rare that this occurs,” Coker said. “This is a very safe place.”

He noted that staff members come and go at all hours and that police have access for security purposes.

But he said the zoo is considering adding surveillance and changing locks and security systems.

“We try to make changes, so that it doesn’t take place,” Coker said, adding staff members are investigating. “The important thing for us is that the animals are fine and everyone was fine.”
