Our poor Midnight hated the car, truck or anything to do with outside for that matter. The most she ever wandered outside the house in her long 25 year life was maybe 20 feet.
Tried to take her on trips because we refused to put her in any "kitty hotel" and it was a pain to find someone to come in to look after her if we were away for long periods. Although quiet during our attempts (except for the panting), she would "loose her mind" during the ride. We would put a fresh potty and her bed in the back seat of the TT but, she was totally confused. She would not lay still, panted, meow'd some and insisted on laying IN HER POTTY and ignoring her bed. Once we got to our destination and put her in the camper, she would be fine after a few hours although not quite the same as being "home".
Sadly, we came home one day to her laying on the floor unable to move her hindquarters. Vet said she most likely threw a blood clot which paralyzed her and she was likely to start having more. We decided that finally, at age 25, with a grim prognosis for her future quality of life, we held her while she went to her last "catnap".
