YUCK -

I think that the first thing you should do is find some articles on the internet that explain why it is so important that you stay away from dirty kitty litter and print them out to show your husband. (I think that guys think that women make this up just to get out of cleaning the box).

second - maybe you should change to one of those brands that are supposed to last longer or is advertised for multiple-cat households.

Finally, paying a neighbor kid is better than the smell of a stinky litter box. Your baby's health is more important than a moment's embarrasment.

good luck.
