* No longer able to reproduce. This is the most obvious difference between altered and unaltered male cats. Neutering prevents male cats from impregnating female cats, which can help to control the population of stray cats.
* Reduced aggression. Neutering can help to reduce aggression in male cats. This is because testosterone, the hormone that is responsible for male sexual behavior, can also lead to aggressive behavior. By removing the source of testosterone, neutering can help to make male cats more docile and easier to handle.
* Less likely to roam. Neutered male cats are less likely to roam than unaltered male cats. This is because they are not driven by the need to find a mate. This can help to keep neutered male cats safe from accidents and fights with other cats.
* Longer life expectancy. Neutered male cats tend to live longer than unaltered male cats. This is because they are less likely to get into fights or accidents, and they are also less likely to develop certain health problems, such as testicular cancer.
Unaltered Female Cats (Intact)
* Can reproduce. Unaltered female cats can reproduce, which can lead to unwanted litters of kittens. This can be a problem for both the cats and the people who care for them.
* May go into heat. Unaltered female cats go into heat, or estrus, about every three weeks. During this time, they may exhibit a number of behaviors, such as yowling, rubbing against furniture, and spraying urine. This can be disruptive to both the cat and the people who live with her.
* More likely to develop certain health problems. Unaltered female cats are more likely to develop certain health problems, such as ovarian cancer and uterine infections. These problems can be serious and costly to treat.
Overall, it is generally recommended to alter both male and female cats to avoid the potential problems that can come with unaltered cats.
