Does anyone else see this behaviour?
Bass, my ten-year old, behaves differently depending on which room she's in.
The bedroom is where she spends most of her time, and she'll happily sleep on the bed with us at night (in fact, I don't think we could remove her from the duvet!). She LOVES being brushed in there and likes a bit of fussing but it only takes a very small sudden movement to make her jump and run off.
She rarely comes into the living room while we're in there - if she does, she'll just wander round and walk out. On the rare occasion she sits down, the slightest movement or noise will have her scampering out again. Can't get near her to brush her or make a fuss. (However, sometimes I find her asleep on the sofa with her sister in the middle of the night.)
Kitchen - will slink in to eat but will scarper the minute either of us goes in or even walks past the doorway (very frustrating cos we end up waiting for her to finish eating before we go in - no good if we're in the middle of cooking!).
The spare room where the computers are is where she's most "normal". It's the only room where she seeks out our company and will jump up and sit on a lap. I can even pick her up and put her on my lap and she'll stay there - just as long as I'm at the computer (she's on me now as I type!). Possibly she has memories of being secure in this room, as it's where she and her sister were confined to they first arrived, (but if that's the case, why doesn't she spend all her time there?). I just wish she could be this relaxed everywhere else.
Her sister Drum has is much more consistent. She's bonkers in EVERY room!
