I got this Informative card at the super-holistic cat food store in Manhattan that I totally forgot about! I found it in my move and wanted to share it with you guys! helpful if you feed your kitty any kind of fish or fishy wet food! I was going to scan it, but I might as well just type it out.
makerel (king, spanish, gulf)
tuna (ahi*, yellowfin*, bigeye, albacore)
Bass (striped, black)
Croaker (white pacific)
Halibut (pacific, atlantic*)
Tuna (Canned chunk, light, skipjack*)
mackerel (north atl. chub)
**=May contain PCBs
Hope this is helpful to any catsters that eat fishes!
