“Cats are smarter than dogs. You can’t get eight cats to pull a sled through snow.” Jeff Valdez.
After I read that, I wanted to check it out for myself. “Mailiiiiin” I shouted, “call the dogs, we need to find out something.” Mailin whistled for the dogs and we tied them to the sledge.
As expected, they pulled the sledge obediently through the snow.
