A feral cat that's terrorizing students has forced an elementary school in Maryland to close.

The ferocious feline is on the loose at Richard Henry Lee Elementary School in Glen Burnie. Animal control officers have set traps for the animal, but have been unable to catch it, Washington, D.C., TV station WUSA reported.

The school was forced to close at 9:45 a.m. ET Friday.

An estimated 500 students were either bused back home or waiting to be picked up by parents or guardians.

According to the Capital Gazette, "the kitty hasn't scratched yet." But school officials weren't taking any chances.

Traps will be set up for the kitty through the holiday weekend.
