A communications device used to summon the SWAT Kats in times of danger. It was similar in appearance and function to Callie Briggs’ communicator, except with a blue button in lieu of a red one. Following the ordeal with the gargoyles at Skycor Towers, T-Bone gave one such beeper to Felina Feral. Although she initially refused it, she was urged to keep it “for luck.” Fortunately, she did, and she was later able to use it to alert the SWAT Kats to danger when she was kidnapped by Otto and Laszlo and taken to Moorkroft Manor.
