6. Cats will let you know when they are sick.

9. Cats are happier and healthier when they are outdoors.
This is not necessarily true. Many cats are happy being outside at certain times, especially when the weather is good. However during bad weather – they would prefer to be inside. But cats are defiantly not healthier when outdoors. The average lifespan of strictly outdoor cats is estimated to be approximately 1 year of age; indoor-outdoor cats about 3 – 6 years and indoor only cats have an average lifespan closer to 13 – 15 years.
