I love reading about the differences in character, it's so very interesting!
Thanks.
Best wishes,

<snip> Bruiser is the baby.  I don't care how big

At least for mine, I think their early life really has had a profound
effect on their present personalities.

Sammy was born here, has only gone outside when supervised, and has
never spent a night outside. Like Brusier, she just can't put on an
effective "scary cat" act. She's always ready to play, and about the
only things that scare her are thunderstorms and the vacuum.

Little Bit is my resident coward. She was a stray, about ten months
old and very pregnant, when she adopted me. I know she had a previous
owner, since she had a flea collar the previous summer. She likes to
go outside, and I let her out unsupervised when I'm home, but she
spooks easily and comes running pawing at the door when she hears a
dog barking or a car driving by. Just about everything new or strange
scares her, although, unlike Sammy she doesn't mind the vacuum and
sits in the window and watching the light show during thunderstorms.

Rocky is ex-feral, and I really don't think he ever had hoomins in his
past. He was 6-8 years old when I first started feeding him, and it
was a long time before I saw more than the end of his tail - maybe as
long as a year before I could pet him. Actually, last fall was the
first time I heard him purr, and just recently was the first time he
jumped into my lap. He's decided that my side of the apartment complex
is a safe zone, and now he approaches people in the safe zone and
gives headbutts, asking for scritches. But, outside of the safe zone
he still runs from people, including me unless I call and he
recognises my voice. He still spends most of his time outside, though
lately he comes in for the night. He's a pretty big cat, and doesn't
seem to be afraid of anything up to the size of the german shepherds
next door. He wanders into the yard next door where there's a chow,
and just ignores the d*g when it barks at him. Even with the
shepherds, I don't know if it's the size, or the fact that there or
three of them.
