While modern house cats have been largely domesticated, many of us often forget that these animals still have a strong predatory instinct. As is often seen by cat owners, cats commonly exhibit behaviors that are associated with hunting and prowling. For this reason, don't be surprised if your cat likes to catch animals and leave them on your front door. While you may feel that it is wrong for your cat to act like this, it is important to keep in mind that this behavior is a product of the instincts that have allowed them to survive in the wild for thousands of years. It is because of these very instincts that Ronan and Emma Lally were concerned when their cat went missing along with some newly hatched eggs. What happened next shocked everyone.
