Outdoor cat lifespan

Reviewed: 2026-09-08 · Model: cat-lifespan-v0.1

Direct answer

In cat-lifespan-v0.1, outdoor lifestyle applies a bounded negative adjustment of 1.0 year before the final lifespan range is clamped to the entered profile.

What outdoor access adds

Outdoor access can increase exposure to traffic injury, fights, parasites, infectious disease, toxins, and weather extremes. The model treats this as risk context, not a diagnosis or a fixed outcome.

How to interpret the estimate

A shorter model range should be used as a planning signal. It can support conversations about supervised outdoor time, vaccination, parasite prevention, microchipping, and routine veterinary care.
