They seem to be related. Similarities include the need to wander, the ability to go long distances and periods of time between refueling, and the habit of returning to where they are coddled. The tom may roam but will always return to the feathered lair. The camel may protest but will remain compliant in the end. Their expressions are steady and do not register what lies within. Maybe there is no change within to be expressed outwardly.
The cat's demeanor does not change during each new hunt, pounce, and the merciless period of toying with the target. Don't know about the camel's, I'll find out.
