Yes, you can offer small amounts of cooked, plain mackerel as an occasional treat. It's a safe protein source that can provide beneficial omega-3 fatty acids. However, because it is an oily fish, it should only be given in moderation—think a few small, boneless flakes mixed into her regular food once a week or so. Too much fat can cause pancreatitis or digestive upset. Always cook it thoroughly without any added oils, salt, or spices, and remove all bones. For major dietary changes during pregnancy or nursing, it's wise to consult your vet first.
