Strange Tomato Damage

Off to Put-In-Bay, where I plan to play a lot of volleyball tomorrow (hopefully)... but before I head out, I thought I'd post pictures of some strange tomato damage that I found this afternoon in my garden, in the hopes that my fellow gardeners could try to help me figure out the cause.  Here is the state in which I originally found the tomatoes as I walked around the yard:

These tomatoes were at least a foot off the ground--way too high for something small like a mouse. It almost looks like the damage was caused by something that may have other large teeth, but have fairly flat teeth across the front.  Either that, or this particular animal is a very careful eater, because the gnawing is fairly even across the face of each tomato:

I asked my gardening assistant for her opinion, but she had no idea what it could be, either.  In fact, she was so guilt stricken disgusted by the sight that she had to avert her eyes:

I know the feeling.  Oh well, at least she was kind enough to oblige me by eating the rest of the tomatoes, so they didn't go to waste.   In fact, they were gone in a flash of black and white fur...

... and white teeth, carefully hidden to make sure that I didn't notice how straight across they are in the front.  Hmm...
