This variant of Owlbrow is much harder than the original, it has over 15 times the health of its predecessor and over double the attack power. Additionally, it can knockback and slow your cats. This enemy can be a pain, particularly in Elite Corps, where it will interfere with your efforts to kill the mighty Mega Cat.
Decent meatshielding will be needed to stall this owl while a stack of ranged cats does work against its massive health. Anti-floating cats with good range like Nurse Cat can effectively control it.
