Strictly speaking, daggers suck.
Give the cleric's favored weapon something...cooler. I can understand you want something light, concealable, but what I would suggest would be the Claw Bracer from FRCS. It's basicly a bracer with three blades (Ala Wolverine) that go over the hand. Since it's an exotic weapon, giving it as a weapon would be free, and it fits the Cat motief.
