Male cats cannot be neutered during estrus. Because the reproductive organs of male cats will be red and swollen during the estrus period, which will affect the normal operation and may lead to incomplete removal of the testicles. It is recommended that pet owners perform sterilization surgery on male cats after the estrus period is over. Before performing a sterilization operation on a cat, it is necessary to check the cat's mental state, appetite, urine and feces, body temperature, etc. for abnormalities, and bathe it in advance within a week before the operation.

Precautions for sterilizing male cats:

1. Wear an Elizabethan ring. Prevent the cat from licking the wound and chewing the sutures.

2. The cat needs to be deprived of food and water for 24 hours before the operation, because the anesthetic will cause the cat to vomit, and if there is food, it will easily block the trachea and nasal cavity.

3. Keep warm after the operation to prevent the cat from catching cold.

4. Take a bath one week before the operation, and do not take a bath for one month after the operation.
