Near-Infinity/EEKeeper to mod familiar.

I am just trying to increase my cat familiar's lockpicking stat to be the thief my party doesn't have. I've tried both Near-Infinity and EEKeeper to change the "FAMCAT" creature,it to FAMCAT.CRE and dropped it into my BGEE's override folder.

When I reload my saved game, there' no change.

I've also tried to import the FAMCAT.CRE into my saved game ("BALDUR.SAV").

Anyone know what i am doing wrong?

I know other people have made familiar mods, however I would like to experiment with more changes to my game in the future.
