The short answer: Yes, but only occasionally.
The long answer: Human-grade duck meat contains healthy amounts of zinc, iron, and B vitamins. Its flesh is generally considered as white meat, but since the bird flies around a lot, its breast meat is considerably darker than chicken and turkey breast. It is also known for having more fat than other poultry sources, so it should be given to cats infrequently.
It is not advisable to feed your cat raw duck meat and raw duck eggs since these may make her sick. If you are considering feeding these to your pet, be sure to discuss the risks with your veterinarian beforehand.
How to feed duck to your cat: Cook the duck meat to 165°F to kill pathogens that may cause food poisoning. Remove and render the fat as much as possible. Never serve your cat duck prepared with herbs, seasonings, oils, and heavy sauces. Salt, onion, and garlic are to be avoided at all times. Take off the skin and bones, then chop the meat into smaller portions. If you are giving duck to your cat as a treat, make sure it doesn’t go over 10% of her total caloric intake.
Offer a tiny slice of cooked duck to your cat before including it in her diet. Observe how she reacts to it in the next 24 hours. If she does not manifest any strange symptoms, you can give her a bit more the next time around.
In summary: Compared to other poultry products, duck meat is made up of a higher percentage of red meat and monounsaturated fatty acid. As long as your cat is not allergic or intolerant to duck meat, she may occasionally enjoy this animal-derived protein.
