What is the minimum size my rabbit’s cage should be?
The minimum standard set by the House Rabbit Society is an ex-pen. An ex-pen formed in to a rectangular shape is 6′ long x 2′ wide equalling 12 square feet of floor space. Your rabbit’s cage needs to be tall enough for your rabbit to easily stand up on his or her legs to periscope around as well as comfortably hop at least three times and not hit anything. On top of this your rabbit also requires at least 3 hours of free range daily floor time but more is always better!
