Fish sticks often contain added ingredients such as breading, seasonings, and preservatives that may not be suitable for cats.
Additionally, some cats can be allergic to fish, and fish is not a natural part of a cat's diet.
Tuna, commonly used in fish sticks, is high in mercury, which can be toxic to cats if consumed in large quantities.
Suggestions
If you choose to feed your cat fish sticks, ensure they are plain, without any added ingredients, and only offer them occasionally as a treat.
Monitor your cat for any signs of allergic reactions or digestive upset.
Consult with a veterinarian if you have any concerns about including fish in your cat's diet.
Note: even if labeled as safe, any food can potentially cause allergies. When introducing a new food, please feed a small amount and observe your cat for any allergic reactions.
