Depending on the distance I would expect the cat to have succumbed during the trip. If the inside of the canister was not open to the outside air it probably wouldn't have enough oxygen and have suffocated during the trip. If it was open, would the amount of pressure in the tubes be fatal to a cat?
If the cat did survive, I wouldn't
want to be the attendant who opened the canister.
