I like a bit of middle ground: one who's shy, but when feeling comfortable, will get in people's faces and say hello, and be a part of the family life. I have three girls: Buffy, the most outgoing, talkative, mischievious little moose we've ever had. She's just great, her only faults are her constant attempts to sneak outside and her tendency to create an opera with my dog, with nonstop squealing and mrowling, with some thumping from my dog getting overexcited and hopping up and down. It creates a racket and a foul mood, lol
Molly is my middle ground cat: she's very shy and timid, is always running from everyone. She's extremely bonded to me, though, and I thought the way she behaved towards me was the same way she behaved towards everyone else, so you can imagine my surprise and denial when I was told that nobody could ever get close to her. I was told that while Molly was cuddled in my lap, purring and snoozing. Molly's just very clingy and "touchy feely" (that is, she likes to touch you with her paws and body, and when you're stroking her, she clenches and flexes her paws as if the pleasure is too great, lol). She's very happy and innocent, though I think she tends to worry when food is concerned. The only time she gets violent is when food is around, and I don't mean in cat fights. I mean, when I'm trying to sleep and she's trying to pry open my eye lids with her claws, eventually reverting to injecting poison into my cheeks. And while I'm preparing the food, she's screaming and hollering, and starts leaping and squealing some more as I walk towards her with her food. Just for kicks (because I've found she's a pretty intelligent cat), I decided to see if I could teach her to always grab for the bowl, and if she touches it, the bowl will be lowered to the floor. I believe it took two meals to teach it, but it wasn't a hard "trick" to teach, really. But she gobbles (*cough*inhales*cough*) her food and goes hunting for more. She heads straight for Willow, knowing the usual feeding spots, and I have to stand watch and protect Willow, who'll let Molly dive in without a care in the world. Tonight, I have Buffy eat on the kitchen table, and when Molly was done, she hopped up there (most times, that's where Willow eats) and she immediately dove in. Normally, she doesn't pester with Buffy, who's the ALPHA GIRL in the house, and Buffy immediately started licking Molly's head, the signal that she's trying to dominate and is about to kick ass in a few seconds. So I put my hand on Molly's chest, to guide her away, and she immediately started growling. It's a rare occurance to hear Molly growl (so rare, I think I've only heard it twice in her life, lol), and I'm not sure if the growl was directed at me or at Buffy. But either way, she had to leave Buffy alone while she went hunting for Willow.
Willow is the shyest, timidest cat we've ever had, and we joke that she's a wee bit senile (she's only 7). She's so fearful and skittish, and if she's bobbing her head at something on the floor, if you touch the thing and move it, even a fraction of a centimetre, Willow will shoot straight up into the air. It's very sad. But even though she's such a scardy-cat, she's extremely territorial. Until we got Buffy when Willow was 2, Willow wouldn't tolerate strangers in the house. She'd stalk them (frequently cornering repairmen in various rooms) and slice at them if they dared touch her (I think she wanted them to touch her; she looked so sweet and nonthreatening as she sat and stared at them). Then we got Buffy and she calmed down. Well, she calmed down towards strangers: she just redirected the aggression at my dog. It was shocking, really; before Buffy came, Willow would rather just hunker down and try to be invisible if Jake so much as walked into the room. She was scared of him. But Buffy was her baby, of a sort, so when she thought Jake was a threat to Buffy, she'd kick ass all over Jake's pretty nose (there were a few nasty fights in the beginning). Heck, I remember one time when both Buffy and Willow were on a bookcase and Jake wandered into the room and started hopping around and squealing, trying to get at them. Willow stood up, stood over Buffy (sort of as a shield) and made like she was going to jump down and kamikaze all over Jake. Jake noticeably calmed down and I forced him and myself to hoof it out of there. After a while, Willow calmed down (probably when she finally assured herself that Buffy had grown enough to take care of herself) and now she doesn't care when strangers walk into the house. She doesn't care when Jake is hovering behind Buffy while she walks throughout the house, though if somebody steps on Buffy's tail (or does something to make Buffy shriek), Willow comes racing from out of nowhere, same as the days of long before, huffing and puffing and ready to murder the offender. If it was Jake who did it, he'll drop his head and wander away, but Willow will be hot on his tail, roughly 4 or 5 feet behind him, tail down and stiff and eyes never leaving his rump, just making sure he isn't trying to double back and have at Buffy again.
