I noticed that Meka decided to kick 1/2 the litter out of the box all over the shower (luckaly the box is in the spare shower) and she did this when we packed up a bunch of stuff and put it in the kitchen just like we do when we leave for the RV on land for the weekend. BUT this time we took the stuff and left her behind.. Of course we were back in an hour and we just went to pack the other RV for camping but I think she thought we were leaving her and got mad...... I vote for the DOg... Debbie
