Cowplant mod?

Something that has always frustrated me about Cowplants is that it's only playable Sims that will take up the offer of eating the cake; you have to direct a Sim to eat it. I believe that if you are cultivating a Cowplant you would (hopefully) not be stupid enough to take the cake. Therefore it seems more logical for me that non-played Sims go for the cake. Is there a mod out there that allows this to happen?
