fish oil for cats?

It looks as though fish oil is good for me. Might it be good for the cats (one with dry fur, one possibly depressed, one young and healthy who might as well get anything possibly useful and harmless)?

I've googled, but most of what I've found is commercial sites. What I want is either scietific studies or personal accounts on a site that isn't biased. I did see a couple of studies, but they were for specific skin conditions. There was also one statement that fish liver oil is a bad idea for cats--too much vitamin A.
