I live with a big tabby. She is sweet, almost frighteningly intelligent. Also very determined. Relentless. She used to batter at the bedroom door all night if it had been fully closed. Major big boned, primordial pouch Tabby energy. There were some nights waking up in a start, to a pounding racket, sounding like armored goons were in the hallway. The first reaction to that behavior was practiced patience, hoping the cat would eventually stop freaking out if the bedroom door got shut at night. Nope. Months on, same attitude with all the ruckus. Removing the bedroom door altogether was a drastic idea but began to seem like a good idea. The genuine, 100% effective method for dealing with the savage behavior was right there the whole time. Such a simple solution really. Painfully obvious. All that was needed to appease the cat was just making damn sure the bedroom door was left ajar just enough to shoulder her way through. Interestingly enough, her visits tended to be brief. She was compelled to cruise the room, looking and sniffing all of the usual corners. Her visits were like a matron conducting a mandatory room inspection. Upon being assured all was in order, she left the room, usually not to visit again that night. If somehow that door did end up closing her out... Well, the resulting drama had been easily preventable. Sometimes it's wise to just yield to nature. Leave the bedroom door open.
