Male cats do not have to be neutered, but the advantages of neutering outweigh the disadvantages. After neutering, male cats can completely avoid indiscriminate breeding, avoid testicular tumors, prostate hypertrophy and other problems caused by estrus, and get rid of the habit of spraying urine to vent and like to run away from home. Secondly, after neutering, cats become quieter and can better develop good living habits. Therefore, without considering breeding, it is best to neuter the male cat, which can reduce the trouble caused by the male cat's estrus period and extend the life of the male cat.

Hazards of not neutering cats:

1. First of all, the biggest disadvantage is that it increases the probability of cats suffering from urinary tract diseases.

2. When male cats are in heat, they will not only make frequent calls, but also urinate randomly at home.

3. Cats in estrus are likely to always want to sneak out of the house due to physiological needs. If the doors and windows at home are not closed properly, the cat is likely to fall from a height.
