Culprit

So, after a great girls day full of shopping, brunch, and lots of laughter, I came home and immediately (like most days) went to check on the progress of my vegetables.... this is when I found this:

This was my FIRST tomato! I was so excited that I finally had one turning red, but obviously something got to it first! :( What a disappointment...
I guess I am going to have to build a cage... or maybe a trap! lol
