Cabbage shredder

Are there any contraptions that would shred cabbage leaves into long strips? I don't want it to be chopped but basically long strips.

We are currently cutting it with a knife in the hope that longer pieces rather than a leaf will help keep our dental bunnies teeth down e.g will he eat it slightly differently. It's worth a try I guess.

If there is will someone please let me know too, I spend hours cuting and shredding spring greens for the bunnies
