Example Input: My dog thinks he was born into the gentry and is entitled to fine dining each evening. Accordingly, he will not eat plain kibble. A scoop of this on his dry food, a little water to make gravy and we're good to go. Ordering a case from Amazon was way easier than picking up individual cans at the pet store, too. All in all, a success for us.
Example Output: 4
