A Kal Kan dog food can.

Kal Kan was a brand of canned dog food that Emmett Brown fed Einstein.

Its slogan claimed it was "Recommended by Top Breeders" and the label guaranteed "100% Complete Nutrition".

Doc had even devised an automatic dog feeder that would open cans of Kal Kan and dump the contents into Einstein's dish.

Behind the scenes

  • In real life, Kal Kan was actually the original name for a brand of cat food, as opposed to dog food as depicted in the movie, from 1936 up until 1988, when the company changed the name to Whiskas in order to give the product international promotion.
