Hello and a warm welcome from Spain.
Its great here, with lots of advice, help, support and friendship.............oh and we have a bit of fun now and then
Cuglie looks a real peach
and I sympathise with your worries about moving.
We flew from UK to Spain and the only way the cats could go was in the hold
My eldest cat Dino has a heart murmer, so we were really worried about him. Pepsi is a more relaxed cat and we rescued Moofi here. My vet in the UK didnt believe in tranquilising the cats for journeys, he said that the cats would go into a sort of "shut-down" mode and they would be fine. So thats what we did, it was very stressful for us all, the cats seemed fine and settled back to a normal way in about 3 days.
Anyway that was 7 years ago now and I am not up to date with the latest thinking on cat-travel, obviously it is different if you are not travelling out of your own country ?
My friend did the same journey (UK-Spain) with 2 cats and they drove, they had the back seat down and put a sort of dog grill between the front and back, they let the cats out during the journey. They had food, water and a cat-lit box in the back with them as well - so all those things were catered for. They stopped overnight at places that allowed pets. So that all seemed to work pretty well.
Well I hope you come up with a satisfactory solution
as you say cant be leaving that cutie behind
