Cats generally like salty stuff...I'd say go for the fat and worry about the cholesterol later!

I use safflower butter, after my health food store expert scolded me for margarine. "It's two molecules away from plastic!" she told me.

1 lb butter, 1 cup Safflower Oil. Blend well and store. Will just be less salty, that's all. (or 1/2 lb butter, 1/2 c Safflower oil [olive is ok too])

Come on, Tiger, take your meds!
