This is another popular myth that people think applies to their cat, especially if they have fallen out of a 2nd story window and survived. The truth is, cats only have one life. To ensure that your cat's one life is a healthy life, take them for regular check ups with your vet. And do not believe those myths by testing any of them out on your cat. It would be a hard and painful lesson to learn the truth about your cat - that it does have only one life. Make it a good one!
