That's cool, I have a pet rat too. He just lives in my walls and steals my food.
Pet Rat Sleeping In Tissue Box Refuses To Wake Up For Anything But Treats

Waking up and getting out of bed: it’s the worst. Enter precious rescue pet rat Bean sleeping in her tissue box and refusing to wake up until caretaker Esther places a bowl of almond slices nearby, at which point Bean immediately stirs and gets up, ready for some treats. Honestly I can’t say I blame her — I refuse to get out of bed for anything but house fires, and even then very reluctantly. ‘But it’s so warm,’ I remember telling my girlfriend as she rolled me off the bed onto the floor.

Keep going for this video, as well as another of Bean waking up for some yogurt.
