All we can do is keep on truckin. Keep putting the word out there. The thing is, we won't ever reach everyone. But if even one learns, and makes better choices for their pet, that's one more pet that will be healthier and happier. And that one will tell people, and perhaps sway just one, too. And so on.
We all started at a point where we didn't know. Now we do. So we just keep on truckin.
