Yes, Maine Coons can meow as well as make other vocal sounds, but volume and frequency vary. Some owners notice chirps or trills; others have a quieter cat. Learn the situations in which your own cat normally vocalises rather than trying to translate every sound into a fixed phrase. It may be responding to a routine, seeking contact or reacting to something in the environment. Look at posture, activity and the surrounding circumstances alongside the sound. A sudden increase, an unusual cry or vocalisation associated with pain, difficulty toileting or distress deserves veterinary advice.
Avoid assuming a change is simply a chatty breed becoming more talkative. Keeping a short record or video can help explain what you have noticed. Respond to the underlying need when you can identify it, while keeping daily routines predictable. When recording an unusual sound for the vet, include the surrounding behaviour and timing, rather than repeatedly provoking the sound to capture a better clip.
