This was the result of a conversation between myself and BennieTiger: we were discussing him lovely wife SueDeer coming to visit him at work, with the resultant mischief. And believe it or not, it wasn't me that suggested the butt-printed building, that was all the tiger's doing, suggesting Sue trying to clean off the windows with her tail and getting a little to close to her work.
From that expression I get the feeling she doesn't feel much regret here. Then again when you're a giant predatory deer, there's not a great deal you need to worry about when it comes to irate city officials: those hooves make short work of squad-cars.
