Thank you very much for your advice.
I have never heard of spook harnesses as our old boys were so laud back nothing fazed them. I've looked them up and as far as I can see there are 2 types - one with two bands and one with three and a grab handle. I assume the three bands plus grab handle will be the best for me (being little and of a certain age) but was wondering what you thought.
When she is stressed food is a definite no no so I don't think that will work at the moment. I do talk to her all the time but without having much effect at present. Maybe in the future.
I hadn't really thought about her not experiencing the outside world very much. She was fostered by a family for a few months but they returned her to the charity saying that they couldn't cope with her wanting to be up all night. I assumed, obviously wrongly, that she would be fairly acclimatised to things outside. She does go to bed at a reasonable hour now and will sleep through so progress is being made there.
We are giving her a specially prepared flower remedy. It's got about half a dozen different 'flavours' in it including the rescue remedy and I have quite high hopes of it making a difference.
Thank you again. I feel that we are doing some things right and you have boosted my confidence in this respect.
