Oryctolagus cuniculus (Flemish Giant breed)
Flemish Giant Rabbit
Flemish Giants are gentle, imposing rabbits whose calm nature is often undermined by owners underestimating the space, handling strength and cost that come with their adult size. They suit experienced rabbit keepers with genuinely large housing.

- Humidity
- Not critical with good ventilation
- Exercise
- Several hours of supervised free-roam exercise daily in a large secure space
- Grooming
- Weekly brushing, more during seasonal moults; nails need regular trimming given the breed's weight
Diet and feeding
Unlimited grass hay, measured leafy greens, small amount of pellets; fresh water always available
Behaviour and compatibility
Digging, chewing, binkying, territorial chinning and thumping when alarmed
- With children
- Supervision essential; its size can accidentally injure a small child during a startled kick
- With other animals
- Can live with a bonded rabbit companion; introductions must be gradual
- Training difficulty
- Moderate; litter training is realistic, recall and handling tolerance take patience
Health
- Sore hocks from inadequate flooring
- Obesity and joint strain
- Dental malocclusion
- Shorter lifespan linked to giant size
Needs a rabbit-experienced vet; standard equipment and dosing may need adjusting for its greater weight
Special care requirements
Housing and carrying equipment made for average rabbits are usually too small or too weak; everything needs upsizing
