If you've shared your home with a Siamese cat at any point, you know very well that it is never a dull moment.
Lonely cats will also meow for attention. Some breeds, like Siamese cats, meow and yowl more than others. Still, there are times when frequent — or increased — vocalization is not normal.
Why does my cat meow so much? She is not a Siamese breed, which I am told meow a lot. She is quiet during the day, but at night, she walks through the house and meows all night. It keeps me awake.
