My oldest cat Dutchess who is about 5 years old will start meowing around 5 am or so in the morning wanting to go outside. Last friday, her and her sister were being butts and got outside before we could catch them before we were going to work and we were upset at them for this so we made them stay out for about 14 hours straight..So atm Dutchess does not want to go outside that much..and she hasn't meowed us awake in the early mornings.
