Feline-focused food puzzles dont have to be complicated

This is my DIY feeding puzzle, preferred by two of my four cats. I modified it with the wooden base after my 11-pound cat would just tip over the original cardboard box that I'd cut holes out of to hold the cups. Make sure the cups are narrow enough so that the cat can't just face plant and eat out of the cup.
