does my kitten need wet food?

[RolandsMom]

I have a kitten (Roland) whose almost 5 months old. At the moment i am feeding him Nutro natural choice kitten food and he is putting on weight and growing like a weed. i have been told by my vet that i dont need to give him wet food but other people have a different opinion. Does he need wet food as well? he is eating on demand right now so his food is out all the time and he eats when he wants to. He has slowed down his eating this month but still seems to be putting on weight. Do they go through eating spurts like children do?
