Your Rex rabbit is stretching out in its cage, but its whiskers are touching the sides. That means the enclosure is too small. Rex rabbits have a compact, muscular body but need ample room to hop, stand on hind legs, and display natural behaviors. Cage size is critical for their physical and mental health.
Our editorial team has researched the specific needs of the Rex breed to help you provide the right living space. Unlike some larger breeds, Rex rabbits have dense, plush fur and a stocky build, but they are active and require a cage that allows for at least three hops in a row.
Minimum Cage Dimensions for a Rex Rabbit
For a single Rex rabbit, the absolute minimum cage size is 4 feet long by 2 feet wide by 2 feet tall. This allows the rabbit to take at least three consecutive hops, stand fully upright on its hind legs without touching the top, and stretch out fully when lying down. Because Rex rabbits are heavier and more muscular than some other breeds, they need a sturdy floor that is solid (not wire) to prevent sore hocks.
If you have a bonded pair of Rex rabbits, double the floor space to at least 8 square feet. Remember that these are minimums; larger is always better. A cage that is too small can lead to obesity, muscle atrophy, and behavioral issues like chewing bars or aggression.
Why Rex Rabbits Need More Space Than You Think
Rex rabbits are known for their calm, docile temperament, but they still need daily exercise. A cage is just the indoor base. They require at least 3 to 4 hours of supervised free-roam time daily in a rabbit-proofed area. Without enough space to run and jump, Rex rabbits can develop health problems such as pododermatitis (foot sores) and gastrointestinal stasis from inactivity.
When choosing a cage, prioritize width and length over height. Rex rabbits do not climb like some other breeds, but they do appreciate a small ledge or hideout. The floor should have a soft resting mat or fleece to protect their delicate feet. Always ensure the cage has a designated litter area, as Rex rabbits are generally easy to litter train.
Setting Up the Cage for Comfort and Health
Inside the cage, provide a hidey house that is large enough for the rabbit to fully turn around in. Rex rabbits are sensitive to temperature extremes, so place the cage in a draft-free area away from direct sunlight. Keep the cage well-ventilated but not in a noisy, high-traffic zone.
For bedding, use paper-based or aspen shavings; avoid pine or cedar due to respiratory risks. Rex rabbits have dense fur that can trap heat, so ensure good airflow. Place a heavy ceramic bowl for water (no bottles, which can be hard on their teeth) and a hay feeder to keep Timothy hay clean. Regularly clean the cage at least once a week with a rabbit-safe cleaner to prevent urine scald and respiratory issues.
