You know when a cat gets a feeling to go out, and that kitty knows where he could go out. Well, it might happen that the before mentioned kitty would try really hard to get through the door he knows leads outside. Obviously a kitty can't get through a thick wooden door, but he just might cause some damage while trying...
I have to admit that these pictures don't really show the reality, which is that the seals of the door are pretty much gone... Now at the summertime it's not too big of a deal, but when the fall and winter kicks in, we don't want the cold air creeping inside.
So yes, guilty as charged. I guess the big one will be cursing me all the way to the hardware store!
