Why does pet food come in dry and canned varieties?
Just like humans, different pets will have different preferences and will seek variety in their diet. In the US, dry kibble provides the largest portion of calories for America’s pets, and accounts for more than 60% of all cat food and dog food sales. Dry pet food offers convenience as it is easier to store and feed. For those who practice free-feeding (letting the dog or cat feed itself throughout the day with the use of a timed device to release food at intervals), kibble can be simply left in the food bowl to give pets enough food to last an entire day, and pets can eat at their own pace without risk of spoilage.
Meanwhile, wet food may be a better option for those with pets that have certain physiological challenges such as missing teeth, poorly aligned jaws, or smaller mouths, or for senior pets that have lost their sense of smell. Pets that are reluctant to drink adequate amounts of water may also receive some hydration in wet food.
