Kitten feeding question

My kittens will be ten weeks on thursday. They usually get free fed dry and they get wet food 3 times a day. The place i get my kitten food from ran out of wet and wont have it till tuesday. So for the last three days they have been eating just dry, and they have all been eating fine.

Is it ok to feed them just dry as long as they are all eating?

Also is it ok to start using a spray bottle on them when they are doing something they arent suppose to? I just dont want to scare them.

Im moving in the next three days, and im thinking of keeping the kittens at my work in boarding untill we are done moving. Im scared they will get out somehow or get stepped on.Will they be ok?
I also put up a sign at my work for them, to find them homes, im hoping people will see them there and someone would want to adopt one. I have homes for 3 so far.

These babies are doing so good, they are so good around the dogs, and they all follow me EVERYWHERE, I cant do anything without a herd of kittens running after me. Its so cute. They are all so friendly too, I've never had such friendly kittens.They purr when you pet them and lay in your lap for cuddles. Im so happy with these guys, there doing so well.

I don't think it would hurt to just feed dry, but it is usually recommended to feed both, wet is generally healthier and less fattening, less carbs, etc...plus it helps prevent crystals and UTIs. But only dry is not going to do any harm or anything.

For the short term, it should be OK, but just make 100% absolutely certain they have ready access to an unlimited supply of fresh, clean water all the time.
