Why is my cat anxious and hiding at night, but normal by day?

Updated On September 23rd, 2025

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.

I am sorry to hear about your kitty! I wonder if something is making him anxious in the evening, such as some noises outside, perhaps a cat in the neighborhood roaming outside, a person in the household who is only around in the evening, etc. I would consider getting a Feliway diffuser (a plug-in product that produces pheremones that calm cats) and starting a calming supplement such as Zylkene or Composure. These products can all be purchased online or in some vet clinics. If you are seeing no improvement with these products I would recommend a trip to his vet to ensure there are no medical issues.
