Pets as a lifestyle statement?

It really would be nice if there was some sort of control, maybe even a one time little class at the least. Maybe just a hour
long giving the in's and out's of pet care, nutrition and exercise. What's bad for your pets and etc. But somehow I don't really
think that will work since half of it is common sense anyways. Unfortunately, I guess there's just not much we can do.
At least they have a home instead of being at the shelter.. But even then, that's not always much better than the shelter.
