They do grow back. Caution - If you do both wings they can still fly. One wing unbalances them.
Unilateral clipping is cruel. Bi-lateral clipping DOES destroy real flight. However, they are still able to get lift and therefore speed away from a predator or from other treats. If they do climb on something (and my ducks love to climb things) a unilateral clip can cause them to fall rather than glide down. Yes they have a semi-version of "flight" but it's much safer for them.
As for the cat, it's actually good that the kitten is growing up around the ducks, as that means they have a better chance of getting along. BUT, there is something you absolutely must consider, is that a good 80% of cats and about 50% of dogs (and humans!) carry a bacterium in their saliva called pasteurella, which is deadly to birds. So you just have to be mindful that the ducks never get into the cat's water, or the cat doesn't bite or scratch them.
