One of my cats has a tendency to swallow most of his dry food pieces whole without chewing, even after switching to bigger sized pieces in hopes that it will force him to chew it, but still nope. In this situation, Is it easier for a cat to digest the smaller sized pieces or does it not really matter and continuing with the bigger size is just as fine? Both brands are about equivalent on the health level (grain-free, low carb, no bad fillers, ect) He will eat wet food but isn't too crazy about it so eliminating dry isn't a choice either.
