Love, J. A. 1988. Housing for rabbits. Humane Innovations and Alternatives in Animal Experimentation 2, 47-48.

In most laboratory situations, rabbits are kept isolated in cages. ... We have attempted to correct this deficiency by keeping rabbits in either large tubs which can accommodate six or more animals or in indoor/outdoor pens. Provision has been made in each case for a covered area under which the animals can run when they are startled. ... The rabbits in the pens and tubs are not as heavy as their more sedentary caged counterparts. They run and skip and sometimes fight although we find that rabbits which have been together from a young age fight less than the older rabbits. .... Disease problems, other than fighting injuries, appear to be less frequent than in the caged animals. Initial studies suggest that hairballs are much less common in the rabbits in tubs than those in cages. ... Tubs [lobster tubs] are cheaper than the traditional stainless steel caging and permit greater behavioural expression by the animals.
