Our 11 month oldf very playfull cat, that always wakes us up at 3:00 AM is very different today. He woke up at 7:00 AM and is now scared of his own shadow and every noise. Though he loves to sit on the screened in porch and play, he is afraid of everything out there too. His diet has not changed and there is nothing new in the house. What is wrong with my little man?
