She's referring to being pregnant because of the whole issue with litter boxes and pregnant women.

I don't think a roaming cat is "stupid", but rather just owned by irresponsible people. I agree with everything else Twisterdog said, but could have done without the graphic part (I'm too sensitive, I know).
