The difference between castration and sterilization of a male cat is that castration involves ligating its vas deferens, so that it loses the ability to have children, but it will still be in estrus and can mate, but it will not be able to mate. Then let the female cat get pregnant. Neutering means removing the testicles and ligating the vas deferens, so that there will be no estrus or mating in the future. The owner can choose to castrate or neuter the male cat according to the specific situation.

Preparation and care for male cat sterilization:

1. Try not to perform sterilization surgery during the estrus period. The reproductive organs will be swollen and congested, and heavy bleeding may occur after the operation. If the cat is developing well and not thin, it can be neutered as early as 6-8 months old.

2. Before performing sterilization surgery, please ensure that no food and water are allowed for at least 8 hours. Vomiting during or after anesthesia can cause food to block the trachea.

3. Prepare the Elizabethan ring to prevent the cat from licking the wound due to discomfort after surgery, which may lead to wound tearing and infection.

4. Prepare iodophor for the purpose of spraying the cat's wounds regularly every day to disinfect them.

5. Do not place the cat in a high place after surgery. If the bed at home is very high, please do not let the cat get on it, because the anesthesia effect can easily cause the cat to fall and affect the surgical wound or injure the cat.

6. You must not catch a cold after surgery, as it can easily cause vomiting and diarrhea.
