Just curious if anyone has any experience with either of these indoor potties? It has been raining for the last 2 days here and suppose to rain for the rest of the week, and Vegas will not go potty out in the rain. Last night she had 3 accidents inside b/c she didn't want to go out. I haven't used the wee wee pads before b/c I originally wanted her to go outside only. I didn't want to confuse her with pads & going outside also, so I was wondering if one of these indoor potties would be better since they have the artificial grass. Has anyone used one of these before? Thanks so much!!
