InSIM 2.6 & Sarah Crittur

Why can't I end Sarah Crittur's initial pregnancy with the 2.6 InSIM Repoductive Adjuster? The only option available is Give Birth. Any subsequent pregnancies can be ended, just not the 1st one. (Yes, I have made pet actions both selectable & cancell-able with my trusty User Startup Cheat file. )

I want to end her "default" litter since it seems to have reveted back to it's pre-Pets-patch defective staus (pups are just Sarah clones with no dad) since installing Seasons- at least in my game. If I can't do this with InSIM, is there another option for ending or (even better) fixing this 1st pregnancy? Maybe with SimPE or....? (Actually I tried looking at Sarah with SimPE but saw no options for setting/ending a pets pregnancy, at least not with the latest version. )

Thanks,
