ENVIRONMENT (cont)
Rabbit caging sizes found in the USDA regulations and those recommended in the Guide are the same except that the USDA specifies how much additional space is required for a nursing mother with a litter. Minimum floor space requirements are listed in the table below. A minimum internal cage height of 16 inches (40.5 cm) is recommended by the Guide. Larger rabbits may require more cage height to allow animals to sit up.
| Weight (kg) | Area (sq ft) | Area (sq m) |
|---|---|---|
| <2 | 1.5 | .14 |
| up to 4 | 3.0 | .28 |
| up to 5.4 | 4.0 | .37 |
| >5.4 | >5.0 | >.46 |
Females with litters require considerably more space.
