@zygote Thank you so very very much for your input and insight. It must be a huge relief to @CatCurmudgeon to have someone else on board, rooting for little Ella.
Consider valerian either in tablet or liquid form for her to take internally for the car journeys, and as a back of the neck drops, which you can buy specially made cat-calming drops, containing valerian (as well as other cat calming ingredients). And also get pet formula Bach Flower Rescue Remedy to squirt a few drops in her mouth. All these things can help enormously for car ride stress, and can even remove the stress altogether. Catnip is an anti-nausea drug as well, so put a cat catnip mouse in her cage with her and/or give her some powdered in a bowl to take as much as she feel she needs.
These things might be a good idea for her to have anyway, from now on.
