Who's been walking in my bookcase?

I've decided to give a few pieces of my furniture a face lift so on the weekend I found the box with the paint tubes in it and decided on a magnolia cream color for the book case in the hall way.

I completed the first coat and told Beauty and The Knight to be careful of the wet paint.

Unfortunately I forgot to tell Tommy.

 

 I think that temptation and curiosity was just to much to resist as at his height, all he has ever seen is a row of books.
Or maybe the other dogs dared him to walk on the empty shelf as he is the only one small enough to fit!
