Hello how may I help you? How much space does a cat need? I can look that up for you. What kind of cat is this question in regards to? Just a pet cat Thank you, and is this the only cat in the home? Yeah just one cat It is recommended that one cat in a home have at least 300 square feet of accessible space. What if I had two cats? The figure is per cat, so having two cats would mean that you should have at least 600 square feet of accessible space. What if they were indoor/outdoor cats? Cats outside a portion of the time require a minimum of 5,000 square feet of outdoor area to be happy, although as they will often roam off the property this may not all need to be in your yard. Okay. Thank you bot.
