Pre-requisite for Undead Master Feat

[LucianC]

Undead Master
You can marshal vast armies of the undead to serve you.

Prerequisites: Spell focus (necromancy), the ability to cast animate dead or command undead.

I have two questions:

Does the Command Undead feat count as being able to cast command undead to qualify for this feat?

If not, does Animate Dead, lesser count?

[Mysterious Stranger]

The Command Undead feat does qualify. The description of the feat even references the feat.

Benefit: When you cast animate dead or use the Command Undead feat, you are considered to be four levels higher when determining the number of Hit Dice you animate. When you cast command undead, your duration is doubled.
