Dry food is recommended.
The smell and fat content of canned food are attractive to pets, but it contributes more to tartar build up. Table scraps are not a balanced diet and encourage begging, finicky eating, and obesity. Avoid generic and store name brands. Although low in price, these foods are made with poor quality ingredients that aren't very digestible. This means many of the vital nutrients aren't absorbed, and much of the food is excreted.
