My house pig has taken to waking up at 2:00AM and 4:00AM squealing for water and/or food. It's a habit now and I don't know how to stop it. I have tried to ignore it, but he will carry on and get louder and louder until I get up and give him something. I work full time and am very tired during the day because of being woken up during the night. It's not like he is a baby that needs to be fed, he's a year old. What can I do? Is there any kind of food that acts as a sedative? Any suggestions would be appreciated.
