We have a Mystery Kitty in our house. Well, her name is actually Pavla (named when we adopted her 5 years ago). She is such a sweet kitty but she is painfully shy. Painful in that my daughter (or anyone for that matter) can not hold her every day like she wants to. She runs and hides when we walk toward her. She will only come to us on her own time and terms. It's sad thinking that she has chosen a life of solitude. We have always thought that she may have been abused in her prior home. Her brother..aka "Blanket kitty"..is SO the opposite. He HAS to be near you and craves and loves attention.
Sophie can occasionally scoop her up and take her up to her room for some one-on-one love (which she does seem to love). These are very rare pictures I was able to capture before she scurried away.
