What is this in these pictures?

I have at least ONE more on a CD here somewhere but so far, I have been unable to find it.. I will ask my daughter how many more she has...

I think if it were the cameras, it would show up in other pictures and not just in aniaml pics but it has only shown up in the ones with animals. She takes TONS of pic's of her grandbaby, born in January and none have shown up in those.. If the camera were going inside and outside immediately before she took pictures, I would agree that it is fogged lens or something but she grabs the camera off the dresser and shoots. All the ones with that in it were taken in her bedroom, with the exception of that one with the dog in it. We just find it facinating...not scary at all to us.

Just a little freaky there Laura! I don't know what it is but it sure is interesting! I hope my kitties have a guardian angel!
