Good Prestige Classes for Rogues

Does anyone go here anymore? I dunno, but it’s worth a shot.

I’m a tenth-level Chaotic Neutral Catfolk Rogue in a 3.5 campaign looking to diversify my talents a bit more. Anyone care to recommend some prestige classes? It would be nice to have some abilities to make myself more useful when unable to get a Sneak Attack in.

I can’t help you GG because by the time I stopped playing D&D prestige classes were still a new idea and we never used any. However maybe the D&D Wiki can help you?
