Day 6, subject was strangely nowhere to be found upon observer's entering of home. Observer searched the entire house, but was entirely confounded as to the location of the subject. Observer suspects that subject was so worn out from being an ornery bastard, that he was sleeping like a rock in some weird location.
Day 7, subject's survival was confirmed via both direct and indirect evidence. Direct evidence: subject presented himself for petting and attention, acting as if nothing weird had occurred the day before. Indirect evidence: a vomitsplosion covered a large portion of the carpet near the downstairs bathroom. Observer can only reasonably conclude the following--subject time traveled out of the apartment on day 6, and upon return on day 7, the time travel's effects resulted in the subject's tossing of his cookies.
Days 8 and 9, business as usual in the subject's home. Violent mood swings (affectionate in one minute, attempting to filet observer's appendages the next) have become the norm. Considering dosing the subject with catnip in order to preserve the integrity of observer's skin.
Day 10, despite the administering of food in regular intervals, subject has decided to destroy a package of treats. Observer believes the subject is in the throes of boredom/depression, and eating everything in sight as a result. Most likely, the presence of the observer in the subject's home for longer durations beginning tomorrow will assuage some his unsettled attitude.
