Reasons for sterilizing stray cats:

1. It can control the number of stray cats and reduce the occurrence of tragedies. If stray cats are not sterilized, they will breed indefinitely, resulting in more and more stray cats on the streets.

2. Reduce the incidence of reproductive system diseases. Neutering stray female cats can reduce the incidence of diseases such as pyometra, and neutering male stray cats can prevent urinary system problems.

3. Avoid adverse symptoms during estrus. Stray cats that are not neutered will frequently go into estrus. Female cats will like to meow when they are in estrus, especially at night, while male cats will urinate everywhere, which will cause trouble to the residents living around them.

4. Avoid infection with sexually transmitted diseases such as feline AIDS.

5. Indirectly extend the life of the cat. Reducing cat diseases can indirectly extend the life of cats.
