Instead of enjoying the much chased-after bone, she left it and went to see why Wawa was locked out! So she waited while Wawa whined and moaned on the other side. Perhaps she didn't like to see her friend in agony. Perhaps she enjoys being tortured by Wawa. The 2 are inseparable so Wawa will not be boarding the plane after all because I think 4 cats are already too much work for my sister. An additional dog will drive her up the wall. So I am stuck with 2 dogs for another.......10 years? Maybe 12?
