My wife and I were renting a home from someone that he knew whose Mother had passed away in. We would look at the cat on the floor and see his fur being petted, it was just the 2 of us, and neither around the cat. We got a puppy and the same thing happened. Also, whenever she was mad at me and was in the kitchen, the fridge door would open and our ghost would throw and egg at her. She would also channel the tv, turn it up, or just shut it off. The radio was also something that she loved to play with. So, they are around and usually very harmless. Or ours was!
