I cant comment on the quality of the product as my elderly arthritic cat will not ingest it, Ive tried everything mixing in food putting on treats.. he is not a particularly fussy cat either.. Judging by his reaction the taste is unpleasant and its been a real pain trying to get him to eat his food with it mixed in and he won't go anywhere near it on its own. The spray bottle is not a good way of administering as often only a fraction of a full squirt comes out so end up having to do multiple pumps, therefore dosing is not accurate at all. Overall am disappointed and am going to try an alternative brand which comes in salmon oil and a dropper bottle for accurate dosing.
