Fish can be a useful option for some cats with food sensitivities, particularly if they need to avoid more common meat proteins such as chicken or beef. Some cats tolerate fish-based diets very well, especially limited ingredient recipes with a single fish source.
However, fish is also a fairly common allergen in cats, especially in cats that have eaten fish-flavoured foods for many years. Because of this, fish is not usually considered a true novel protein, and it may not be suitable for every sensitive cat.
I have tried to checking ingredient lists carefully for the foods listed here, as some fish foods still contain chicken, poultry fat or mixed animal proteins. There are also many ‘complementary’ fish foods available. Watch out for this carefully as they are designed for treats only and are not nutritionally complete so shouldn’t replace meals. I’ve avoided listing these supplementary foods here.
