The first cat we were owned by was Milky Way. Flash back to 1986 (as evident with the very old console tv)....Milky Way is 4 months old and into and under everything. He was pint size when we brought him home...the boxes in front of the tv were to keep him from getting under it....he was a perpetual 2 year old.
Flash forward to 1987 Milky way is now 1 year old and no longer pint size he is about 10 lbs. and very tall. Every morning when I would go into the kitchen, I would find that he had been quite busy overnight. He opened drawer below the oven and the cabinet doors as shown in this picture.
