Excuse me, I don't know much beyond FFX, so please enlighten me:

Who is Cait Sith? What FF is he from?

I Think He is an agent in shinera...and Cait Sith is only a robet and he is controlling him.

Moving to FF7 forum.... Please try to post in the right place in the future.

sorry, didnt know where he was from...

Oh, right... In which case you have to decide whether you want people here to spoiler you the whole game, or if you want to play it yourself...

Its definetly a guy from shinra i just forget his name i think his name began wih an r or something. i hope was of some help

if you all MUST know, his shin-ra name is Reeve, he's a dude with a cool lookin goatee!

cait sith is a cat robot on a toy mog being remote controlled by reeve!

SPOILERS i think
I thought the one who controled Cat Sith was Tseng Well i guess i was wrong oh well SPOILER i think

**Spoilers**

It's Reeve for sure. I cannot fully remember but at one point Reeve is taken captive at Shira and Cait Sith says something which Reeve then finishes. They were both in the same line.
