CompLastStand makes an animal increase its attack speed as it loses health, with a configurable upper limit because we don't want a divide by zero error when it dies ;)

    //A comp class that makes animals scale their melee cooldowns the more damaged they are

    public float finalCoolDownMultiplier = 2f;

It is a comp class, so you just add it in XML in the <comps> tag. For example, this allows the Muffalochicken in Vanilla Genetics Expanded to increase their attack speed as they are damaged:

<comps>
	<li Class="AnimalBehaviours.CompProperties_LastStand">
		<finalCoolDownMultiplier>6</finalCoolDownMultiplier>
	</li>
</comps>
