Title: Cat and dog door

Description:
The Invention is for the pet and owner in which the both can benefit from the Invention. The door allows the pet to freely enter and exit the room with out bothering the owner. Each entrance is of the size for the best user of the door. The intendance is sized to fit in both a sliding glass door and window. The difference is depending on model. The window version is just for cats and is one size with the exception of different paneling or screen for air exchange. The window version comes with a pad for the outside of the window allowing the cat to have a pad to jump on before entering the window door. The sliding glass door model has two sizes because of the different size of pets. This model has options of metal paneling. Plexiglas paneling or screen for ventilation. The height and width are uniform with sliding door entrances.  
      The process for making these Inventions is as follows. Aluminum bar stock of two kinds and two colors one aluminum finish and one bronze. One bar stock is same grooved channel on both sides with the other side flat finish. The other stock is grooved and channeled one side the side used for the installation of the sheet metal stock or wire screening. Then there is round ⅛ th  dia. Rope type of rubber holding cord that holds the wire screening in place and is installed in the grove of the bar stock. The wire mesh screening is roll stock type cut to fit. The rubber insert holding is from roll rubber glazing stock. Then there is the doors the doors are made of plastic simulated to look like wood and is of brown finish. This is also from sheet stock cut out to fit the size made for the pet door. The hinges that hold the door in place are simple hinges of ⅛ in. thick and the ¼ in. screws that comply with the hinges. Then there are the rip bits fasteners that hold the parts together.  
      The bar stock is measured out to the specification in the drawing figures of the Abstracts of specifications, and then cut to the lengths specified. They are cut at the 45 degree angles to be fastened together. Depending on the model is determined whether the paneling is inserted before the square stock is installed or not until. Thus if screen is the model then the bar stock is installed after the sheet stock is installed. After all parts are cut to the measurements and angled at the degree then it is put together with rabbit like fasteners. Then the handle is attached by screws. The plastic sliders are affixed to the top in the channel. The rollers are affixed to the bottom in the channel to allow sliding back and forth to be out of way of the user.  
      All the parts come to the table of assembly then put together in sections allowing the assembler to adjust to fit before the holes are drilled in place so the fasteners can be installed. Then as the assembly goes down the line it is welded with wire fed aluminum braised (Meg flux) at the bar stock section of the cross bar that holds the door sectional and the bottom of the screen or panel in place. Then the door is installed and the handle is installed. Then the castors rollers are installed and then the plastic slides are installed. Inspections are done to insure quality control before boxed and shipped out.  
      This Invention is different from the pet door installed in a regular door of a house in that it is placed in the sliding glass door area and in the room window.
