Oh Behave

Does your cat need to go outside to be happy?


It is a common belief that cats need to go outside to be happy. In fact, cats can lead fabulous lives indoors. Indoor cats live two to three times longer than cats who go outside. 

Here’s what cats miss when they don’t go outside:

  • Fleas, ticks and worms (Ewwww)
  • Being attacked by another animal (Ouch and cha ching!)
  • Being unintentionally poisoned: Rodent poison works up the food chain; ingesting the poison itself, or an animal that has eaten it, may be fatal for your cat (Devastating)
  • Being hit by a car (Heartbreaking)
  • Being lunch or dinner for a coyote (Too painful to contemplate)

Indoor cats appreciate an environmentally enriched home that will keeps them stress free and healthy. Read the full Tails of Marin Article about keeping your cat happy.
