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.

Housing and environment

Housing
Very large hutch or indoor pen, at least 3 x 1.5 m of usable floor space given its size
Space requirement
Considerably more floor and run space than standard rabbit breeds require
Temperature
10–21°C; large body size increases heat stress risk above 26°C
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
