Most of your kitty's diet should be a nutritionally complete cat food, but you can give
them a treat from your plate every once in a while. You just need to know how
to choose feline-friendly snacks with nutrients they need. And if you do give
them fish, be sure it isn't raw.
Meat
Cats are meat eaters, plain and simple. They have to have protein from meat for a strong heart, good vision, and a healthy reproductive system. Cooked beef, chicken, turkey, and small amounts of lean deli meats are a great way to give them that. Raw or spoiled meat could make your cat sick. If you wouldn't eat it, don't give it to your pet.
Whole Grains
Oats have a lot of protein per calorie, and they're easy to make. Many cats like corn, and polenta, a coarsely ground cornmeal, has a good texture for them. You can try brown rice, barley, and wheat berries, but you may need to mash them first. Cats tend to like smaller grains like millet and couscous. Just make sure any grains you give are cooked so your kitty can digest them fully. Whole wheat breadcrumbs are OK, too.
Fish
Fish have a lot of omega-3 fatty acids, which help your cat's eyes stay sharp as well as help with arthritis, kidney disease, and heart disorders. Canned or cooked fish is fine for a treat. But don't share your shashimi or sushi with raw fish. Raw fish in general isn't a good idea.
Cheese
Cheese is a high-protein snack that's fine for your cat in small amounts. But the protein in cheese is less "complete" than the kind in meat, fish, and eggs. Also, many cats' tummies can't handle dairy, so go easy on the cheesy treats, and skip the saucer of milk.
Foods Cats Shouldn’t Eat
Steer clear of these foods when sharing your snacks. They're toxic to cats:
Chocolate
Grapes and raisins
Onions and garlic
Macadamia nuts
Bread dough
Alcohol
Xylitol, an artificial sweetener found in sugar-free gum and candy
Don't let curiosity, well, you know. Keep foods not meant for your cat in a place they can't get to them.
