Poor Salem! It does sound like he is sick, and his symptoms could be caused by a respiratory illness, heart disease, heartworms, or cancer among other causes. It's quite serious when a cat is struggling to breathe, and should that happen again tonight, I would have him seen by a vet immediately. Otherwise, monitor him tonight, and take him into the vet first thing in the morning. The vet can diagnose what is causing his symptoms, and can treat him for them.

Thank you for using Petco Pet Education Center, formerly Petcoach! Your cat sounds very sick. You should take him to a veterinarian as soon as possible. Being out of breath could mean a problem with the heart, lungs, or even blood issues such as anemia or other problems. Unfortunately, there isn't anything I can recommend on the the internet. He needs to be assessed by a veterinarian in person.
