Listening to yowling at night can be incredibly frustrating for you and others within earshot of your noisy cat. I’m assuming that your male has been neutered. If not, that procedure could help alleviate the problem.
Over the years, I’ve lived with quite a few cats that have yowled at night and during the day. In my experience, two root causes are usually to blame: hyperthyroidism or slight dementia associated with old age. Your cat is only 6 years old, so the latter likely isn’t the underlying cause of your pet’s behavior. Have your cat checked out by a veterinarian to see if its thyroid values are up. A simple blood test can provide this information. If so, medication can help curb your cat’s yowling.
