When Siamese cats want attention from people, they often request it with their loud vocals. Their characteristic sounds are different than typical feline noises. Not only are their voices louder, but they also have less consistency in pitch and tone. Siamese cats frequently depend on deep meow sounds to get things from their owners.
Feline breeds that possess ample energy levels are associated with frequent meowing behaviors. Siamese cats, like their fellow Oriental breeds, are thought to be particularly vocal.
