My birdies' bedtime routine includes a song:
Good night my little birdies, good night.
Good night my little birdies, good night!
Good night my little birdies, good night, good night.
Good night my little birdies, good night!
It's sung while the cages are covered up. Sammy has his own routine; he comes out and snuggles up my bathrobe sleeve for about an hour before he's returned to his cozy. He gets very upset if he thinks I will pass up his routine.
Neko, our cat, takes me to bed around 11 o'clock. I snuggle her while watching a little more TV. There's nothing like a drowzy cat to put you to sleep!
