I also have two indoor declawed cats, they are named Thelma and Louise as they are partners in crime.  We got them when they were about 5 or 6 weeks old from the pound (they are litter mates) they will be 5 years old in  November.  Thelma has always been a lover and thinks she is a lap dog.  But Louise had a broken paw when we adopted her and had such a bad cold and infection her eyes almost exploded and she is half blind now.  Needless to say all of that made Louise people shy.  She loves cat trees and HATES to be petted or touched. There would be days when I hadn't seen her for 24 hours or so and I would have to search the house for her, just to make sure she was still alive.  Then my mother in law came for a visit last summer.  And Louise would just follow her and sit on my inlaw's lap.  We were all shocked as she had never done that in the 4 years we had had her.  Then when my mil went home Louise decided she liked being petted and is always on my lap now.  Who knows what changed for her, but she now is never more then 3 or 4 feet away from me.
