Overview

Kittens can start exploring outdoors safely once they’re around four to six months old and have been vaccinated, neutered, and microchipped. Gradually introducing supervised outdoor time helps them build confidence and develop natural instincts while keeping them safe. Studies show that secure, controlled outdoor spaces are a great way to let kittens explore without the risks of roaming freely. This balanced approach helps reduce dangers like road traffic accidents, which cause over 60% of kitten deaths in the UK.
