I'm sure Liz will be able to give you many pointers Jacqui but, for the record, my input for what it's worth .........
I've read your previous posts concerning Lucy's previous disappearance and wonder if her pal (your dog) is coming with you? Sorry if that's a sore point
but he might help to chill her out a bit? A feliway plug in and some zylkene in her food (starting a week before the move) may help to take the edge off what will be another little trauma in her life. What's the new accommodation like? House and garden? How secure/safe is garden? Close to a road? These things would influence your decision.
I would do my
utmost to keep her in for as long as she/you can bear it (even for a day or so
before the move in case the comings and goings involved in the move disrupt her) but, having said that, I do fully understand how impossible some cats are ........
Gandolf (now departed aged 18) came to us aged about 3 from the RSPCA. OH chose him as he was climbing the cage and in obvious distress at being locked up. He had been there for 6 months. We took him home with advice to keep him in for 3 weeks which we fully intended to do until he started throwing himself at the window
We let him out within the hour
This is not something I would recommend at all unless you really have
no alternative. He was however a complete nutter. Thanks heavens he didn't run off but he could so easily have done so.
By the way what is it with the name Lucy? My friend also had a crazy gal called Lucy. Lucy conjures up the notion of such a sweet tempered, friendly gal. Perhaps people think the name might somehow influence the semi feral behaviour?
Very best of luck with the move at what must be a very stressful time for all concerned
