Cats should not have their four canines removed. Removing a cat's canines, especially the four canines, can seriously affect the cat's health and well-being. A cat's canines are essential tools for biting food, particularly when eating fish or other foods that require breaking bones.

If a cat's fangs are removed, its chewing function will be affected, potentially leading to indigestion, malnutrition, and other problems. Furthermore, a cat that has lost its fangs will experience a significant reduction in its hunting and self-defense abilities.
