Encourage people to
- Check there engines before starting the ignition
- Beep the horn
- keep your cat indoors in cold temperatures; they wouldn't be out there looking for somewhere warm to curl up in to.
- Maybe spraying something on the place where the car stands could
persuade a cat to seek more attractive places. (like catnip at the catty door)
- Spray a 'Cat deterrent' at entrance points to your car...
(Vinegar spray is a great homemade cat deterrent. Just mix equal parts apple cider vinegar and water and spray areas the cats love to hang out. It will neutralize a lot of the cats' calling cards and improve a cat's disinterest in a particular location.

Many people have come up with an awesome idea... not sure if it has been motioned yet?
- Electronic tagging; Whenever a cat comes near the car, a warning light is lit within the car; And whenever a cat removes itself to a safe distance the light goes out. (now technically if we put an electronic device to the collar on each cat, this would only really solve half of the problem considering it is not just your own cat or your neighbours... it can be homeless cats too... so this wouldn't really help that much at all.
I think a better solution would be a heart beat sensor or something... something that senses heart beats and tells you not to turn on your engine, or better yet it prevent you from turning on your engine.... because some horrid people don't actually care for other living beings and would just ignore the warning and use pathetic excuses i.e in a hurry??
