Indoor vs Outdoor Lifestyles

Understanding Cats as a Species

• Cats are obligate carnivores and must eat meat. It is a biological necessity.
• Cats play the way they hunt. Stalking, chasing, pouncing, grabbing, and “bunny kicking” are all natural predatory behaviors.
• Cats have highly developed senses. A cat’s whiskers, vision, hearing, smell, toe pads, and tongue all provide critical environmental feedback.
• Cats are built for movement. Cats have powerful muscles designed for climbing, sprinting, and jumping.
• Cats are crepuscular, meaning they are most active at dawn and dusk.
• Cats are control-oriented. They have a strong innate need to feel safe and in control of their environment.

Lifestyle Options

Cats can live in a variety of environments. Each option carries benefits and risks. The goal is to balance safety with appropriate enrichment.

Indoor Only

The cat lives entirely indoors and does not have access to the outdoors.

• Benefits: Lowest risk for infectious disease, parasites, and trauma.
• Risks: Boredom, obesity, muscle loss, stress-related illness, or behavior concerns.

Indoor with Supervised or Protected Outdoor Access

The cat lives primarily indoors but has supervised or protected outdoor time, such as on a harness and leash or in an enclosed catio.

• Benefits: Increased stimulation and exercise while maintaining safety.
• Risks: Slightly increased exposure to parasites or disease, depending on setup.

Indoor/Outdoor (Unrestricted Access)

The cat has unrestricted outdoor access, either by being let out or through a pet door.

• Benefits: High stimulation and autonomy.
• Risks: Increased risk of infectious disease, parasites, injury, wildlife conflict, and trauma.

Outdoor Only

The cat lives exclusively outdoors and does not reside inside a home with people.

• Benefits: High environmental stimulation.
• Risks: Highest risk category for disease, parasites, injury, and shortened lifespan.

Key Takeaway

Cats thrive when their biological needs are met, and their safety is prioritized. If a cat lives primarily indoors, enrichment is essential. If outdoor access is provided, risk mitigation is essential.

Simply Cats Adoption Policy

Simply Cats requires adopted cats to live indoors. Outdoor access must be supervised or fully enclosed, such as a secure catio or harness walk.

Standard backyard fencing is not considered protected access. Cats can climb wood, metal, or vinyl fences, dig underneath, or slip through small openings.

Unrestricted outdoor access increases the risk of injury, infectious disease, parasites, wildlife conflict, vehicle trauma, toxins, and human harm. On average, indoor cats live substantially longer than cats with unrestricted outdoor access.

Our goal is to support safe, enriched indoor lives that meet cats’ biological and behavioral needs while protecting their health and longevity.
