You can give your kitten fish such as sardines, tuna, and canned salmon (beware of fish bones) only as a treat from time to time. Occasionally cooked meat such as boiled chicken may also be offered, but beware with cooked bones, condiments, sauces, onions, or other toxic foods for your cat.
Equally important is to know that raw meat and bones contain bacteria that can make your cat sick. Any raw food offered to kittens should always be fresh. Avoid feeding raw meat until the kitten is 20 weeks old to help prevent certain nutritional deficiencies during growth.
Likewise, avoid raw meat products marketed as pet food, bone-in products, hot dogs, sausage meat, and processed meats, as they may contain sulfite preservatives.
You can also offer a small amount of finely chopped vegetables. But it’s essential to remember that cats are carnivores, which means meat is necessary, so a vegan or vegetarian diet won’t meet their nutritional needs.
