Example Input: We are Chocolate Moose & Mickey Moose,  Our nice owner bought this great food for us.  We love it very much, I have gained 5 lbs. because I eat all of Mickey's food when he isn't looking!  Our skin and fur is much better now too.  :)
Example Output: 5

Example Input: Ordered 2 cases on different dates and got them within 2 days. Cant find these in the stores so please keep them in stock. Make for a great meal with some veggies or a salad...and this type of fish with omega 3's is good for you.
Example Output: 5

Example Input: I like the idea behind this product, but the taste was just too sweet for me, and it has a strange aftertaste. While it has no added sugar or corn syrup, there are plenty of calories (135 for an 8.3 ounce can) and carbs. Also, looking at the price, I think it is way too expensive-almost a dollar a can. I would chose flavored seltzer over this any day.
