Another question...we ended up getting her soil to fill her litter box last night and she used it. :-) Buuut...when do I know when she's ready to be trusted to use it all the time? Before she was pooping on our living room floor in the same spot (did it twice). I keep her closed in the bathroom at night (she loves her little bed set up in there) with two litter boxes, but I'm afraid if I let her out I will find the same mess in the morning.
