The other night Jersey was just beside herself and Steve is running for the flashlight. He swears that he and Jersey saw something move. Who knows maybe they did. Now the dog is down at the heater vent barking and growling at it. Steve ever so brave has the flashlight shining it on the vent. Me I got the stethoscope and listened with the light and the dog. Nothing. Good thing cause if it was another squirrel I was outta here. 2 squirrels in my house in one life time is enough. NO More! We still don't know what it was.
