Welcome to PT and congrats on your 2 new kittens!!! It sure sounds like Pepper may have a URI (upper respiratory infection). This is very contagious as Soapets has already said. You should also go around your home and make sure that it's kitten proof. Please put away things like rubber bands, twist ties, string, needles, or any small plastic or other items that the kittens might accidently eat. Also be sure that any medicines are tightly closed and all pills are in kept in tightly closed bottles and put away. Just child proof your home and this should work. It sounds like you have all the supplies you need. Just give them lots of love. I'd love to see their pictures and I look forward to hearing more about them. I hope that everything goes well with their check up. Please keep us updated.
