I've been reading more and more about how canned food is better for cats - cats evolved eating meat, not corn and other grain-based fillers that are a large part of dry cat foods. Dogs are OK with grains, but cats are true carnivores and grains are not a normal part of their diet. I personally believe the excess carbs in grain based cat foods is a contributing factor in the rise of obesity in housecats.

Most people feed dry because it is more convenient. It is not necessarily better for our cats, and in fact could be worse. However, I am not an animal scientist and am only going by a few (convincing) articles I have read.

I do feed dry, but supplement with canned. If my Abby would eat canned (she refuses it) I'd prefer to not feed any dry at all.
