I have a kitten that I found outside, he was in pretty bad health when I found him, but we took him to the vet and fattened him up, although we still got more fattening up to go. This kitten is very affectionate! He loves attention, and purrs when anybody picks him up. He's not like any other cat I have had. So I was wondering if this was a personality trait, or a way of showing his appreciation.
