Many cat owners feel guilty about keeping their cats inside and worry they are depriving them of natural instincts. Generally speaking, a cat that spends his entire life indoors will live many years longer than a cat restricted to the outdoors. On top of the parasites and potentially fatal diseases it can contract (including feline leukemia and feline AIDS), your outdoor cat is always at risk of being struck by a vehicle. It’s a myth that going outside is a requirement for feline happiness. Playing regularly with cats and providing them with entertaining toys can easily satisfy their stalking instinct, keep them stimulated, and provide the exercise they need to stay healthy and happy.
