I've had the same thing happen and believe its the batteries also. Last year I had a camera hung in a remote are up in a tree 15 ft point down at a wallow, I got pictures of the bear molesting the camera for 2 days before he finally ripped it off the tree and dropped it into the wallow. More than anything else, I have a ton of pictures of bears looking or sniffing my cameras. Doesn't matter what I do to cover my sent, using rubber gloves, etc... so it has to be something about the camera making the smell and that would be the batteries.
