I think this song follows (of course) with the general theme of "The Incident" album which is about varying incidents of some tragic event - from the perspective of those most affected by the tragedy.
In the case of "Bonnie the Cat" The tragedy is a breakup - where a pregnancy is involved. To make things more more tragic, the pregnancy was used by the woman as a type of relationship "ransom," her "last resort" and a type of "gold against" her soul - or in other words, a way to add value to being in a relationship with her. So, tragic because the woman tries trapping the man with a pregnancy.
A third level of tragedy is, that the the attempt to hold the pregnancy as a type of relationship ransom, not only doesn't work to keep the man - but tragically leaves him unaffected - cold and uncaring - while even he understands the gravity of the situation and knows he should care more. Instead of caring he's hostile, angry and disaffected.
This is is all from the man's perspective, so he knows he should care, but he's surprised by how little he is affected: "can't feel the pain that I expected... " And despite the intense drama of a breakup complicated by a pregnancy, like an emotionless machine, he routinely drives away and leaves her anyway, "I put the key in the ignition."
He shows he understands the gravity: "I know what will be" but again other than being unable to sleep - he leaves the situation anyway. And again, judging from the song's intense tone, he's also feeling very hostile under the circumstances.
