Our youngest kitty "chose" us at the humane society.
She literally reached out through the bars and snagged the sweater I was wearing to get my attention.
Then my husband asked me to come look at another kitty farther along in the room - and she just was pitiful, crying and pitching a fit until I came back to her cage.
The shelter worker got her out of the cage for me, and she snuggled up in my arms and went to sleep.
The funny thing was, this kitten had been listed as "not friendly" and "need to watch". They weren't going to let us adopt to begin with, because the observatio time wasn't up - but my inlaws volunteer at the shelter, so we were able to kind of push it through anyway.
When we were making our case to take her home I just looked at the manager and said "does she look unfriendly?" She purrs so loud you can hear her in another room!
