Well, they have been with us last since last August, so if they aren't used to the place by now, they never will be!

However, the only other animal we have is a turtle so I don't think it's him that is making them bark. And no, it's not every day... just about every other though.
I'm thinking it's either them dreaming, or Dharma overcrowding Lily (she tends to sleep ON Lily, rather then beside her). Neither of them seem particularly distressed when we come running in, but its hard to tell with them sometimes.
You're right, I'm not going to worry to much about it. Dharma's fur biting has improved (she's looking shaggier every day in the back end, which is much better then the bald patches she had a month ago), and Lily is a booger as always. However, I think I'm going to borrow a friend's static nightvision camera and record them for day or two, just to be sure.
