Been there, done that.

The worst part is cleaning up the dozen footprints where DD#2 stepped in it, realised it was gross, and then ran around in a circle going "eww" until it was off her feet and THEN came and told us :rolleyes"

For carpeted houses, I prefer the more solid kind of poop you can just pick up, not the squishy kind that soaks in. I am SO hiring a carpet cleaner just before we move out ... no point doing it any sooner.
