I cannot believe some of the things that some of you are calling this creature. There are different species of fox and they all have different features. I live in the swamps and the whitetail deer down here are a lot smaller and have different colors compared to a whitetail deer that you would find in Iowa. The same go with fox, rabbit and squirrel.
The picture that was posted is definitely a fox. Some fox have furry tails, some have skinny tails, some are greyish looking, etc. Please check the following link and compare with the fox that was posted.
