na she uses the box on her own. just make sure you don't change her diet or she will have an upset stomach. when the weather is good she prefers taking her business outside. i can't believe you came back home empty handed. i wanted one and i didn't care which one they gave me. you know i almost didn't get her because she was not that friendly. lol. i adore her now. she runs to hide whenever she sees me because i tease her way too much.
