Every once in a while female cat will be born sterile this means that the cannot have kittens does mean is not alive since it reproduce?

That's not true! A female cat being sterile doesn't mean she isn't alive.

Here's why:

* Sterility is a medical condition: It means a cat's reproductive system doesn't function properly, preventing her from getting pregnant.

* Life and reproduction are separate: Animals can be alive and healthy even if they can't reproduce. Many animals and humans are infertile for different reasons.

* Sterilization is different: When a cat is spayed, it's a deliberate procedure to prevent pregnancy. While this means they can't have kittens, it doesn't mean they are not alive.

So, a sterile female cat is still a living and valuable animal, just like any other cat!
