It could just be a misnomer too, which is quite common. One of my local pet shops was selling a "buttery" corn not too long ago. It was obviously a butter. I gently corrected them. LOL.
You're right...there's no such thing as enough....that is, at least until you finally have too many animals to take care of without hiring a staff of professionals to help you out. LOL. With two dogs, two cats, two corns, two bearded dragons, three crowntail betas, and two 55 gallon tanks filled with all kinds of crazy south american cichlids, I'm almost to that point. haha.
