Cosmic wolf that is classic! I have 4 - so far : p all completely different in personality, all have claimed my couch lol (it's a huge leather L shape and they love it to bits, big mama always falls asleep with her head between the cushions : ) Big papa jumps from his enclosure to my sholder when ever I open the door even if I'm just cleaning water dishes lol, Freddy is a sholder boy and would stay there all day if I let him and Nim is a sook who is spoilt by miss 6 so is a snob to me bahaha
I'm not big on letting them roam on the floor as they always manage to find stuff the vac missed, they're all really inquisitive I like having them on the couch as it's a controlled space and they can't take off under cabnets etc...but they do all try jumping off the couch so thinking of making a 'safe play area' for them lol they have had a few wanders and seem to like my daughters doll house couch : p
I find they let you know when they have had enough, but I do believe they enjoy the interaction - mine pace when they want out - they have they're own way of letting you know you just need to learn they're signals.
