I have no clue Emily!!! That just made me laugh! I am so sorry. I know it is probably not funny, and the last thing you want or need to deal with. But I can see my N doing the same thing and she would try and lie to about it... already. She tries to blame things on the Cats!!! For us it is her doing something to her body, glue, pens, ink, stamp pads, soap, dirt...
I hope it doesn't cause any problems... the things these kids find to mess with. ugh
