During the day, Charlie and the other cats come and go inside and outside. Often we leave a door open while at home. But sometimes, the screen door does get closed. And that impeedes cat entry or departure. Oh My. Well Charlie has developed a unique way of telling us he wants to come inside. Instead of just meowing, he climbs the screen door. We now have a special screen door with industrial grade metal mesh just because of Charlie. Sound unbelievable, well here is the proof.
