A) If one of the bowls does not fit, the top of the Neater Feeder is probably upside down. For shipping purposes, youíll find the top bowl containment section of the system placed upside down over the bottom section. To use the system, simply turn the top section right side up (youíll see the Neater Feeder logo embossed on the back wall when youíre holding the top part correctly), set it on the water catch basin, and place the bowls inside their openings. You will notice the front of each part is curved, so be sure the curve on the top section is aligned with the curve of the bottom section. When the feeder is set up correctly, the extra capacity water bowl will fit into the hole.
