He recently has all his teeth taken out fot stomatitis, as well as some moth eaten teeth they found before taking the others out.
He is not this sweet normally. He was too stoic to catch the pain he was in previously.
Bonus post surgery not happy picture. 
My understanding is that if the food is easily swallow sized, they may unintentionally crunch as they maneuver the food around their mouths to position it to be swallowed, but not out of necessity. If the food is larger, sure they'll break it up so they can swallow it easier. But by nature, cats aren't animals that need to chew food for grinding and digestive purposes (like animals that have flat/grinding molars.) As long as they can swallow it, they don't need to chew.
