Pet's info: Cat | American Shorthair | Male | neutered | 8 months and 8 days old | 10 lbs
Hello, So I have been noticing over the past 4 weeks that my Male cat has displaying substantially different behaviors/mood that cycles between day and night. I would even go so far as to relate the extremity as Jekyll and Hyde. During the day, he's sociable, energetic, affectionate and genuinely happy looking. But once the sun goes down I'll find him hiding in a corner and making distress sounds and displaying a threatening posture. But the following morning he returns to sociable self.
