A mother, any mother, will do anything to protect her young. This is true for humans and animals alike. The Torah forbids us from abusing this divinely instilled instinct. This, then brings us to the connection between shiluach haken and honoring parents, and the reward for long life associated with both commandments.
Parents are the source of life. We are, therefore, obligated to honor our parents. But Rabbi Fohrman takes this one step further. The connection between shiluach haken and honoring parents is this idea of honoring the unconditional, unlimited love that a mother has for a child. If you do honor that love, the source of life, your own life will be strengthened.
