I don't buy them fish cat food anymore...First of all they preserve fish ( meat also but dosage is higher for fish) with ethoxyquin (which is actually a pesticide & isn't allowed for food for human consumption except some spices). And second of all, because there is a potential of mercury presence...
Of course I will never know if the cat food I now give my cats doesn't contain any of them, because for example meat/fish could be preserved with ethoxyquin even before they come to the manufacturer & so it may not appear on the label..But I try to avoid at least the ones I know !
Giving cat fish food occasionaly probably won't do much harm..But I wouldn't feed them with only cat fish food.
You can search for fish, mercury & ethoxyquin on the internet & make up your own mind !
