Half and half is simply half whole milk and half cream. In the UK, they call it half cream. According The Kitchn, half and half typically has a 10 to 12 percent fat content, which, it stands to reason, means it's less fatty than cream and fattier than milk.

Most wet food has offensive ingredients as well. Most dry food has grains - by the way cats and dogs don't eat grains, peas, squash, etc. We purchase grain free dry pet food, buy whole chicken and cook it - less expensive than canned food and more healthful. An egg yolk is also good for cats - not sure about dogs. Lots of fresh - non tap water as well.
