In nature, mother mammals who don't want their offspring simply leave them to die right after they're born. It is NOT natural for all mothers, all of the time, to want to protect their offspring -- food shortage, too many offspring simultaneously, mental or physical illness of the mother, illness or deformity of the offspring, environmental stress, etc., are all common reasons for mother mammals to ditch their offspring. Abortion is a way of getting the same result as nature, only earlier, when the fetus still lacks the capacity to be aware of the process or to feel pain/suffering.

Ok, I hear ya.
Good argument.
But do other mammals have the option of putting their offspring up for abortion?

There's a huge difference between humans and other animals (at least in my family) and between abandonment and acting with the intent to kill (although, each may end up with the same results.

Humans have reasoning, communities of individuals who will take in a child who's abandoned, and a recorded history to show the effects of infanticide and separating women from motherhood on those communities.
