I strongly doubt that you NEED a cybertruck.
Go with the smallest vehicle you can get away with. For moving house or buying a big couch or sth you can rent a bigger vehicle (a van is probbaly more practical in these situations anyway).
Smaller vehicles are just so much cheaper in maintenance, EVs even more
Cats are (at least genetically) used to much bigger and more open areas. So no, a house probably doesnt feel that huge like the relative bodysize would suggest.
