That's a great question! We researched shaker lids extensively before launching pawPairings the reason we do not have the holes you're referring too is because we varied the size of the "sprinkles" from granular to a little chunky as we found through testing pets enjoy this most. We found that the lids with the holes didn't allow that variation as the chunks would get stuck. I have even tried the lid with that has the holes on one side of the lid and the larger on the other side. I tried to sprinkle, but the pawPairings would not come out as well.
When you are using the pawPairings the best way to use is to gently tap the lid with your finger to sprinkle on the food.
