Providing safe outdoor access for indoor cats significantly improves their welfare by enabling natural behaviours, sensory stimulation, and exercise that cannot be fully replicated indoors.
The welfare benefit of safe outdoor access for indoor cats is significant and well-supported by evidence. Cats motivated for outdoor activity who are confined without adequate substitute enrichment develop frustration, obesity, and stress-related conditions. Catios and secure gardens provide the sensory richness of the outdoors — smells, sounds, weather, insects, birds — without the traffic and predation risks of free-roaming. Even partial outdoor access (a secure balcony, a cat tunnel to a garden enclosure) dramatically enriches the daily lives of indoor cats. The investment in secure outdoor structures pays welfare dividends across the lifetime of the cat.
