We cant figure out what happened!?

My sisters and i were all playing with our stuffies and our mini tennis balls and running around and all of a sudden daddy saw blood on Truffles Neck!

He totally freaked out and called my mommy cause she can always figure out (and fix) EVERYTHING. And on top of that... blood totally freaks out daddy.

Anyway, it wasn't super bloody like daddy had implied but there was a little bit of blood. So mommy took Truffle to the bathroom and cleaned her boo-boo a little bit (it didn't require very much cleaning)

this is what Truffles neck looked like after mommy cleaned the area with warm water:
The wound is too wide to have been done with one of our claws while playing as well as too wide to have been done by one of our teeth but mommy still cant figure out how it happened.

As you can see from this photo, Truffle's neck and chest are practically bald so it isn't like she has very much protection for her delicate skin...but we are totally baffled as to what could have happened. mommy said that it looks like a rug-burn like what she used to get when she played on the carpet when she was a kid but the shape and location of Truffle's boo-boo make that impossible. Mommy suspects that when Truffle was running around and squeezing between a box and the sofa (its a tight fit) she rubbed her neck on the box trying to squeeze through.

this is another picture of Truffle after the wound happened. You can see it's odd positioning. Something odd has also happened to Truffle's tail...about one inch from the tip it has decided to bend...like the shape of the letter "L". her tail is totally normal right up to that point and then it makes a sharp left! It's totally weird!

What are your thoughts? Have any of you ever had mystery boo-boo's? Please share with my mommy cause she's ready to make us live in a bubble nothing can happen to us!

Thanks for your help...
