J.M. Smucker -- the megabrand behind Folgers coffee, Jif peanut butter, Pillsbury, Crisco and its namesake jam -- announced this week that it would pay about $5.8 billion to buy Big Heart Pet Brands, maker of Meow Mix, Milk-Bone, Pup-Peroni and Kibbles 'n Bits. That's following last year's $2.9 billion gobbling-up of pet-food lines Iams and Eukanuba by Mars, the candy titan behind M&M's, Snickers and Skittles -- a deal that bulked up Mars' pet-brand portfolio, including Whiskas and Pedigree.
