that worked, thank you very much.

I can't download this.  Mediafire says it is unavailable.  Does anyone have it?

Actually, I'm pretty sure its not the litter thats the problem.  Its a parasite that is often found in cat feces called toxoplasmosis and it can be contracted in many ways, but te easiest is by having contact with cat poo.  Because it is unhealthy to both the expectant mother, and the unborn baby, I can understand why this behavior was not included in the game.  Maxis obviously didn't want any pregnant women to think that this was safe to do.
