It also has a lot to do with what they get used too.
Mine don't even wake in the day now, unless I wake them.Or start passing out treats, a sound they know all too well.
Funny, I had a friend in the other day showing her the kits.She was amazed as one by one each cage came to life from the sound as I gave the Mom and Dad a treat.
Let Hubby start up a saw or even the air compressor, and they don't budge.
Take them out of their room and it's a whole other story, I'm their knight in shining armer. They cling to me like leaches.
Except for the ones who are used to being taken out.They want down no matter where they are.
So use it when you need it, but they will get used to just about anything.
If you want them people friendly you have to get them used to it.
I have one chin I have to keep out by the door, as he pouts if he can't see everything.
He'll take a scratch from anyone, but will let you know to whom and when he will come out.
I am the only one who gets to take them out under protest.
