I went directly to Innova's website. They actually have a place where you can enter your info and it will tell you where it is sold in your area. I found one down the stree from my house and didn't even know it was there! Here is the link that I found...

Petfooddirect.com also has it...but I would look in your area first...shipping isn't cheap because it is so heavy!! Good Luck!
