Customer's feedback to George Tan, owner of Joy Doggy Pet Shop resulted in a better designed safer play pen for his new puppy owners. 1. The home-alone puppy pushes the rectangular play pen (4 pieces of fencing) into a diamond shape. Then the playpen collapses on the puppy, trapping it inside until the owner rescue it after coming home from work. 2. The puppy pushes the play pen, disrupting the newspapers laid on the floor.  This becomes messy. Urine from the newspapers used to paper-train the puppy leaked to the marble or tiled flooring. 3. The Aluminium tray was invented to resolve the above problems. 3.1.  It holds the playpen in a fixed safe position. 3.2.  Prevents shredded newspaper from flying around messing the house or apartment. 3.3.  Prevents urine staining the flooring. 3.4.  Acts as a permanent toilet area for the puppy. Playpen fences can be removed. 3.5.  Rust-proofed and long-lasting. 3.6. Rounded edges prevent traumatic injuries to the puppy.
