It isn't because you are tired, it is because your blood lacks oxygen. When you've been idle too long and suddenly move, you can find yourself yawning later on. That's why a person yawns after waking up in the morning. Yawning adds oxygen to the blood. If it bothers you, try deep breathing.

If one cat yawns does the other one yawn too?
Not normally. If kittens are telling each other that they will not harm one another, they sometimes yawn instead of the usual slow blink. In that case, they both yawn one after another.
