Consuming animal products doesn't inherently lead to animal cruelty. It's the fact that the vast majority of these products are produced through factory farming, which has little regard for the animals, in the search for the most efficient manner of farming possible. This does lead to animal cruelty. On the other hand, it is definitely possible to consume animal products ethically, if they are raised on a small family farm which genuinely cares and takes time for their animals, and doesn't take every shortcut possible to produce more.
