Cows’ anatomy is not well-suited for navigating stairs. Their knees don’t bend like human knees, making descending stairs difficult. Also, their hips aren’t designed to shift their weight backwards easily, which is necessary for going down steps.

  • Stairs are a human invention, designed with proportions and slopes that suit human legs. The average staircase slope exceeds 35 degrees, which is too steep for a cow to manage comfortably.
  • Cows prefer flat surfaces and struggle with slopes. They can manage a 20% slope, but anything steeper, especially at entrances or exits, presents challenges.
  • Evolutionarily, cows haven’t adapted to stairs. They are not naturally equipped for the steep slopes and unusual leg movements required for stair navigation.
  • While cows can physically walk down stairs if forced, they generally avoid them due to these difficulties. They instinctively choose to avoid situations that challenge their physical capabilities and prefer to stick to flat surfaces.

In essence, the combination of cows’ physical structure, their evolutionary background, and the human-centric design of stairs results in a mismatch that makes descending stairs a difficult and undesirable task for these animals.
