The can was first patented in 1810. Since then it has gone through several evolutions, and today there are more than 600 sizes and styles of cans being manufactured. Can manufacturing has grown into a US$14.9 billion business annually, and to this day cans remain the easiest and least expensive way to transport perishable foods—they're lightweight, stackable, tamper-resistant and keep food nutrient-rich, according to the Can Manufacturers Institute.
While dogs and cats continue to reign supreme, the growth of the “other” pet space can’t be denied: 9.9 million homes own a bird, 6.2 million homes have a small pet (usually small mammals) and 5.7 million homes own a reptile.
