Seems to work
I have two cats, different hair types, only one of them brings up fur balls... Or fur turds actually. They look more like they've come out the back end. They both can shed quite a bit.
Both seemed to have a reduction in shedding after eating this for several weeks. Also the fur balls stopped too. They also seemed to enjoy it more than the basic chicken or salmon. With the other ones they often seem loathed/bored to eat it. Whereas with this one they get stuck in without resistance and I saw none of the rejection behaviour you sometimes see with the other flavours.
