I don't know when the cereal stopped production. I did do a online search a while back and found that Ralston Purina was bought out by "Nestle", and then it was called "Nestle Purina". This is the same company that makes the dog food. I work in retail and came across some dog food about 3 weeks ago. What I find interesting is that the outer packaging said "Ralston Purina". It still had their checkerboard logo and was based in St. Louis, just like the address printed on the cereal boxes. So, I don't know if the company got started back up or what.
