Abstract

Prototypes for new housing systems satisfying the most important of these basic needs of the animals were developed. Along with newly introduced socialization programs [they] contribute to improved animal welfare. .. Mice need to be able to rest, hide and build nests. Appropriate and sufficient nesting and bedding material must therefore be available. They also have a need for complex and challenging surroundings, e.g. to work for getting access to the feed. .. Mice are nocturnal animals and have a need for darkness. ... Rats are social animals that need a structured and enriched environment with access to both hiding places and viewing places, as well as opportunities for rearing, gnawing, digging and grooming. .. Guinea-pigs are social animals that should be housed socially in small groups. They are relatively anxious. It is important for all individuals in a group to be able to hide at the same time. Another important need is access to hay used for occupation and feed, as well as for hiding. ... A basic requirement for rabbits is the ability to exercise, which requires sufficient space. .. Dogs are social animals that need to live in harmonious groups. They need predictability.
