Granted its a cartoon, but something always puzzled me....
The Flintstones are a "modern stone-age family", and have all the conveniences of the modern world. These include appliances such as trash compactors, garbage disposals, radios, washing machines, dicta-birds...all manner of modern stuff.... which are essentially powered by animals. Everything from mini-mammoths to pre-historic pigs to itty bitty dino birds, there are a lot of these "Appliances" around which they use every day.
Considering there is no electricity (and these creatures wouldn't run on it anyway), but they should be powered by something .... How exactly do these "items" get their power? Do the Flintsones have to feed them regularly?
It's never been elaborated on in the cartoon; figured somebody must know something.
