I fell asleep last night while watching a movie. I was awakened at 4:00 AM by both cats jumping on to my bed and landing near my head. The TV remote was right by my face and both cats were standing side by side, staring at it with wide eyes. Their little noses were switching like crazy, like they could smell something too. At this moment, I heard a very slight hissing sound and wondered where it was coming from. I picked up the remote, which doesn't have a cover on the back, and my fingers made contact with the batteries. One of them was extremely hot and burned my finger. The plastic part on the outside of the battery was melted, and I realized the faint noise I heard was from the battery. Needless to say, that battery has been safely removed. I'm fortunate that the battery did not explode (not sure if that actually happens) or start a fire in the bed. I guess the cats are too!
