Forum:Can fast headcrabs and poison headcrabs be domesticated?

Could fast headcrabs and poison headcrabs be defanged and domesticated? It is never stated how exactly the fast headcrab gains control as they dont have fangs like ordianry and poison headcrabs. Why does it not show more people with pet head crabs? It seems like they would be the "it" thing. There would of coarse be a rissk involved with collecting them but someone must or else who defanged llamar? Dr. Kleiner was not a vet.
