Thanks for your response.
Jewel is 6 years old now. As a kitten she was adopted by another mother cat who was nursing kittens a week or so younger than her. She barely had her eyes open at the time. I still have the mother.
Jewel herself lived with my mother-in-law for awhile. She stayed with her while we were away and we could not find her when we returned, so ended up leaving her with her. She loved Jewel dearly, but is now in hospital - prognosis uncertain (is 88) So consequently, Jewel is back with us. Her and her 'adoptee mother' are not getting along either now, to complicate the issue.
The only trauma I can think of, other than her being adopted is the plane trip here. I moved to NS and she was flown along with her new mom when she was about 6 months old. She was still suckling at the time. She was nervous and fearful from the time she arrived. When my (now) husband came to visit on the weekends she would hide away but yowl often during the night.
Last night I took her upstairs and brushed her on the couch beside him. He patted her too. She wanted to leave, but when I finally let her go actually hung around for a short while. Perhaps if I keep doing that?? She spends her time mostly under the bed in the spare room downstairs.
Any help or suggestions?
