A photo might have caught a ghostly cat in front of exercise equipment. The feline face is quite perceptible!
"This picture was taken in my basement. Our house has a lot of activity and I have several ghost images. The people that lived here before us had a tabby cat. We have dogs and a ghost cat. Where the cat appears is the base of my treadmill. I have the original of the picture taken before the one that I sent to you. You can see the cat is starting to form." - LWalland
