You can give Charlie an L-lysine supplement - this is an amino acid that has been shown to help the immune system fight off respiratory infections more effectively. Enisyl and Viralys are both good brands, and can be purchased over the counter without a prescription - just follow the dosing instructions on the label based on your cat's weight.
