It started with Lucy. Back when she was on normal diet, what seems like forever ago, she loved her large lab pellets. In particular she liked to play with them before eating by taking them into her Wodent Wheel and running, while her large pellet rolled along, making a terrible racket... On and on. I finally cut out the bottoms of the holes, all the way down to the track, so food would fall out quickly.

Then Dora would store a huge pile of grains in her wheel after cage cleanings, also making noise when running.

Basically it makes wheel washing MUCH easier without disassembly and helps hard food bits fall out quickly.
