What it often means
- A clock: if he was fed or cuddled at 5am once, the voice comes back at 5am.
- Boredom: too little play and hunting during the day, the energy comes out at night.
- A request for contact in a cat left alone all day.
- In seniors: hyperthyroidism, high blood pressure, pain, disorientation. The meow is then louder, more lost.
