My guy has taken to barking around 3am as well. I live in an apartment building and that's about when my neighbor gets home from work and decides it is a good idea to make as much noise as humanly possible... :banghead: anyway, I usually just let him bark it out and if he doesn't stop after 10 bouts of barking I usually go and get a glass of water and check on him, usually he'll just start bouncing around his cage and thinking it is playtime. I tell him to be quiet because "Mommy wants to sleep and you have plenty to do in there". Some times if I turn the TV on and put the sound on low he'll keep quiet and occasionally he watches the TV, he likes horror movies. Long story short, I'm pretty sure it is normal and they just want attention.
