Yes when they are sleepy and tired
They probably just woke up. People yawn when they wake up too.

It's not necessarily bad when you yawn frequently. A lot of people associate sleepiness or exhaustion with yawning. It may also mean you have a lack of oxygen. That could also explain why people yawn a lot when they first wake up. It's because when you are asleep, you don't breathe as often; just deeper. so, if you yawn frequently, you probably need to catch up on your sleep. I hope this helped
Well, a lot of the time they were only in a very light sleep mode, so a small noise can wake them up. They can then wake up feeling refreshed but alert straight away. They do this when they are only staying somewhere for a little while, or are wanting to look out for danger, therefore they can wake up straight away and be awake. When they are in a deep sleep and are woken up they will almost always yawn and stretch, and perhaps stay still for a while. It is just the cat's nature to be very awake when they wake up.
Yes , when you yawn you take a slow and deep breath that brings more oxygen to the brain. the oxygen gives your brain cells a little wake up call.
it is believed to be a way for the body to bring in more oxygen and rid itself of load of carbon dioxide. Other theories suggest that we yawn to wake up, or to induce relaxation.

A person yawns as a response to the lack of oxygen in one's bloods stream usually, but, depending on situation it varies. For example in the morning, it is to boost the oxygen intake so as to wake you up or in class, to get rid of your drowsiness.) We yawn when someone else yawns because your body thinks that person is responding to a drop in oxygen in the room thus you yourself yawn to increase oxygen in your own blood stream.
Stay up late. (:
Yawning upon waking can be a way for the body to increase oxygen intake, regulate body temperature, or signal a transition between sleep and wakefulness due to changes in brain activity. It is a natural physiological response and usually not a cause for concern.
You yawn, stretch, and drink a cup of coffee.
People yawn, because its the fastest way to send air up into your brain, so if you were tired and your not thinking well, you would most likely yawn to get your brain working better.
