Pet cats should not eat fried fish. Fried fish has a high oil content, which is not good for the cat’s health. It will irritate the cat’s gastrointestinal tract and easily cause the cat to get angry and develop tear stains. Feed fish to cats, just boil it in water, no seasoning is needed. If there are hard and thick spines in the fish, it is best to remove them before feeding them to the cat, otherwise the cat's throat and gastrointestinal tract may be scratched by the spines.

Which fish cannot be eaten by pet cats:

1. Tuna. The fat in tuna can cause indigestion in cats. If a cat eats tuna that has been kept for a long time, it will cause histamine poisoning and symptoms such as diarrhea, urticaria, and vomiting.

2. Yellowtail fish. The belly fat content of yellowtail fish is relatively high, and cats are prone to indigestion after eating it. Moreover, the bones of yellowtail fish are relatively thick and hard, which can easily scratch the cat's throat and gastrointestinal tract.

3. Squid. The "thiamine enzyme" in squid will destroy vitamin B1. Vitamin B1 is crucial to the health of cats, so do not feed squid to cats.
