How much fish-based canned cat food is too much, for a cat who eats both dry and canned food?
We feed our cat both dry food (Orijen
, mostly chicken-based) as well as canned food (Weruva
and Tiki Cat
). Both brands of canned food have a lot of fish-based varieties, as well as some others. We've been basically buying "one of each" and rotating through them, but that results in him eating a lot of fish, and I've heard some vague statements that this can be bad. I've gotten mixed answers when I've asked people about it.
He seems to like all of the varieties equally (he really loves them all, unlike many other brands), so it wouldn't really be a problem to adjust the proportions by buying more of the non-fish ones, but if it's not necessary, I'd rather not (mostly because it adds complexity for us in planning how much to buy and how to rotate it).
I'm curious, does anyone know the truth
about whether eating a lot of fish-based canned food is bad for a cat, and what the rough threshold is? Should we be doing 3/4 non-fish? Is 1/2 and 1/2 ok?
FWIW, I've already done a lot of research and reading on canned vs. dry food -- I'm not especially interested in debating that further at the moment :)
