The use of environmental enrichment is becoming more and more common, in order to accommodate innate physiological and behavioral needs such as social contacts, resting, nest building or exploring.
The use of enrichment should not just arise from ethical reasons but also from the proven fact that less stressed animals result in more reliable scientific outcomes, as guidelines and many scientific papers attest:
- Directive 2010/63/EU of the European parliament and of the council of 22 September 2010 on the protection of animals used for scientific purposes
“Establishments shall have appropriate enrichment techniques in place, to extend the range of activities available to the animals and increase their coping activities including physical exercise, foraging, manipulative and cognitive activities, as appropriate to the species”.
- Developing and testing a novel cage insert, the Mouse House, designed to enrich the lives of laboratory mice without adversely affecting the science

In the Amousement portfolio are now available the new Mouse Mezzanine and Mouse Pouch Loft.
The first one fits the standard wire bar lid and gives the third dimensions for the mice to explore. It is available both in clear polysulfone and red polyetherimide.
The second one is designed for facilities with Automatic Watering System that choose water pouches for special applications. In fact, it works as a loft in AWS cages, but if turned of 180° it can accommodate the water pouch.
