Firefighters from the Annandale Hose Company were conducting a training exercise at the Hunterdon County Emergency Service Training Center not knowing that the kittens were inside.
One rotation was just completed inside the building when a member of the Training Facility found the kittens.
They were immediately removed from the smoke and fire-filled building and taken to a waiting ambulance.
Members of Clinton Rescue were able to then give the kittens some much needed oxygen.
All of the sweet kittens are doing well and picked up by a local pet rescue.
There's no word on where the mother cat was during the fire.
