Context: I scrubbed my kitchen floor yesterday because one of them still does n't understand the concept of the litter box . Not sure which one yet . They all seem to think the food dish is a bed and toy as well , so I ' m thinking they 're all using the food dish as a one stop restaurant , potty and inn . I think I ' m getting Elizabeth into dance class next week .

Option 1: None of the above choices .
Option 2: Their daughter is leaving a mess in the house .
Option 3: All of their cats ignore the litter box .
