Are nestle 'chocolate oats and more' bars suitable for vegetarians?

The only thing I would be concerned with is the "whey powder". Whey is usually a byproduct of cheese production, and is the liquid remaining after milk has been curdled into cheese by means of "rennet". Rennet is sometimes extracted from the 4th stomach of slaughtered calves, and since whey is leftover from this, I would watch out. However, most companies now use vegetable or artificial rennet-which are vegetarian.
