Mostly likely the caterpillars of the cabbage white butterfly. They can strip any member of the cabbage/kale family down to the veins over night. The only real prevention is to cover them with a fine mesh so the eggs can’t get laid on there to start with.

It happened to mine this year too. Unless you catch it right away it’s a pain.
I had a little luck with need oil spray, but not really.
