Word of warning - if they sit in your lap while you are driving be careful.
Cats do not love a ride in the car the way dogs do. If your cat decides to hide in your lap while you drive - make sure you have a nice absorbent bath towel. Poor kitties get stressed and lose control of some bodily functions. No problem if you are on a short drive. Big problem if you’re going to be driving for hours in warm weather.
Cats shouldn’t be loose inside a moving car, period. A claw in the wrong place at the wrong time can be a recipe for a fatal accident. A cat should always be transported in a safe, secure carrier that is strapped down and can’t slide around inside the vehicle.
