This is a divider to separate feeding bowls on the PAPIFEED branded dual automatic pet feeder. There's also a good chance this would work for other brands of feeder with similar designs. 

One of my two cats has a tendency to push her head into my other cat's bowl while they're eating, so this divider solves that issue. 

The piece slides between the two bowls and has a slight friction fit. If the piece won't stay in place, there are two recesses on the front designed for 8x3 magnets that can be used alongside taped/glued magnets underneath the stainless removable bowls. Mine has stayed in place the last couple weeks without the need for magnets, so I left them out. 

All exposed corners have been rounded or chamfered to avoid injury. I included a .STEP file in case you need to adjust the width/height of the divider.
