Getting hit by a car is a common cause of injury and death of domestic cats, but few studies on road accidents have been done. A pilot study on the longevity and causes of death of cats in the United Kingdom found that road accidents were the fourth most common cause of death and that cats killed in accidents were on average younger than those that died of other causes. In the current study (conducted between March 2000 and February 2001), 6 U.K. veterinary practices collected data on 117 cats involved in accidents and compared them with data reported via owner questionnaires on 1070 other cats to ensure that the cats that had been in accidents were representative in terms of age, sex, pedigree status, and coat color. Cats that had been allowed outdoors but had never been in an accident (796 cats) were used as controls.
