What does it mean when they hiss. Puddin does it all the time...that is how I know she is awake. I never really thought about it before because she seems comfortable enough when she does it. I just assumed she was calling to Brett. Anyhow if anyone else's gliders do this or know what it means, I would appreciate it. By the way Brett know has ME totally trained. If I don't let him out of his cage fast enough he starts barking until I let him out. He also does this if I don't leave him out long enough even if it is past 2 in the morning and I have to get up early for work...what a brat!
