I've got this cat outside on my porch now. I think it's one of my neighbor's. He keeps howling so I put out some food and water since it's so cold and any water is certainly frozen outdoors. He inhaled two fistfuls of food and now he's still howling at my door. I've offered to let him in, but he's weary of all the commotion in my house and I can't stand there with the door open while he keeps running in and out it So, he keeps howling outside my door.
