Right again, h2o. When I was in school, we had "a" fat kid. As in, one. A single fat kid, an anomaly. I still remember, he was (not unkindly) known as Butterball. Now we're doing good to have "a" skinny, or healthy, kid.You are correct about the epidemic of fat pets. I think it is just too much. Giving them treats constantly and over feeding.
The epidemic of obese kids and the high rate of diabetes in this country is basically because of all the processed food we eat. Eating whole foods it is much harder to overeat.
