  1. The range of behavioural opportunities for many of the animals listed above will be increased by enriching the environment with accessories.
  2. Raised shelving should be taken into consideration when assessing the total floor area.
  3. Temporary (up to six days) rehousing of adult rabbits in smaller cages than specified above should be considered as acceptable.
  4. The above recommended stocking densities are insufficient for the housing of marmosets.  Marmosets must be housed in cages sufficiently large enough to allow for natural movements, such as climbing and swinging.
