Q: Is it best to put mu cat in a basket even when travelling by car?

Answer: Yes, any cat being transported should be in the securely-closed container, whatever the means of transport. Cats which are allowed to travel loose in a car may suffer impact injures if the car has no swerve or stop suddenly. They can also cause accidents by distracting the driver’s attention (e.g. by climbing onto the shoulder) or by getting under the driver’s feet so that he cannot operate the break pedal. And a cat that decides to make a dish for it through an open window, or as soon is open, is often lost for even in unfamiliar terrain.
