Why Do Animals Hide When They Are Sick or Dying?

With thousands of years of animal instincts in their genes, even long-domesticated creatures exhibit the behavior of hiding when they're unwell. A pet who is sick or dying is liable to hide his symptoms and even hide from his loved ones, and for a combination of reasons. It isn't because he dislikes you or wants to avoid your company; it's because he's programmed to stay away from other creatures when he is in a state of poor health.

  1. Hiding From Predators

    • In the wild, prey animals are extra vulnerable when they're sick or dying. The best strategy, then, is for the animal to hunker down and avoid any contact with other creatures, lest they pose a threat. In some cases, this may mean finding a warm, safe place to hide while the animal waits for death -- in less extreme circumstances, the animal may just need a place to hide while recovering from an injury.

    Comparison Between Animals

    • Even pack animals, who would theoretically benefit from the protection of kin, are liable to hide an illness or injury. Again, this is because of the threat of predation. When the animal is traveling with others, showing weakness or injury would easily mark him as a target for predators, who would be all too eager to exploit the situation. By hiding symptoms and lying low among other members of the pack, the animal protects himself from being singled out.

    Pain Management

    • Sick animals may hide simply as a way of avoiding physical exertion. Animals experience pain and sickness much the same way humans do; while they may prefer to hide their symptoms, they also take rest whenever they can get it. Excess sleeping and lethargy are common symptoms of pet illness. Finding a place to be alone is a way of saying "do not disturb."

    Watching for Trouble

    • If you notice that your pet is avoiding you or hiding, look for other symptoms that may indicate illness or worse. For example, your pet may show signs of stress, like shivering or struggling to breath. He may move sluggishly, eat less than normal or exhibit abnormal bathroom behavior. Pay close attention to signs like these, because your pet may attempt to hide his symptoms and hide from you.
