The reasons why cats still meow after being neutered:

1. Cats will express their emotions through meows, and meows within a reasonable range are normal. Cat owners don’t have to worry if everything is fine with their cat.

2. If a cat emits a howl similar to that in estrus, expressing a courtship signal, it may indicate that the cat's sterilization surgery was not complete, and the cat still has sex hormones in its body and will howl.

3. If the cat makes a painful cry, it may be that the cat's physical condition is abnormal, and the owner needs to carefully check whether the cat has any disease.

4. The cat may be bored and howl to pass the time. Cat owners can prepare some toys for their cats to pass the time.

5. It may be that the cat wants to attract the owner’s attention and hopes that the owner can play with it.
