When we go on camping trips (usually 3-4 days) "Grandma" comes and visits twice a day, she cant' bear to think that her little one is left alone. I've tried to tell her that once a day is fine, check foods, litters etc. NOPE, litters done twice a day (which I do anyways-he's fussy) and she entertains him and he loves it. Of course, he loves it when we come home too. My cat would not know what to do if he was left alone for so many days, he is a social bug.
