I have taken down the first camera - it has only captured possums, birds and a fox. I don't think there is a cat in that area anymore. I might consider putting it back in a few months but right now I don't feel there is a point to feeding the possums.
The second camera came up with better shots but they are still whited out - I think they are reflecting off the bottom of the trailer. I put the food out in the open and hope that will help. The batteries are running out so I will have to replace everything there tomorrow night.
