Environmental Enrichment

Shepherd Specialty Papers ALPHA-twist

Add a little “twist” to your rodent cages! ALPHA-twist is a carefully crafted, multi-layered paper nesting material that is chopped into short lengths for rodents to unfurl and manipulate into a fluffy nest. It’s soft and comfortable and encourages species-specific behaviors. ALPHA-twist also ensures the elimination of confounding variables. The virgin bleached paper pulp it’s comprised of ensures that it is clean and consistent from cage to cage, batch to batch, and lot to lot. ALPHA-twist's unique, tightly rolled and uniform characteristics allow it to dispense quickly in a consistent manner. It’s free of chemical contaminants, mycotoxins and endotoxins. It’s also ideal for toxicology and GLP studies. 

8 lb box, 18 lb box.

Enrichment is Key to Animal Welfare

Just like humans, animals need a chance to exercise their minds and have control over their environment. And like humans, lab animals also enjoy toys and treats! That's why environmental enrichment is key to animal welfare—minimizing boredom, stress and stereotypic behaviors such as pacing and rocking. It's as essential as proper nutrition to the well-being of the laboratory animals under your care. 


Enrichment products offer animals experiences similar to those they encounter in the wild, such as the opportunity to nest, build, forage, explore and exercise. The result? Happier, healthier animals! 


ASAP offers edible, non-edible and enhanced enrichment for all species. We will work closely with you to recommend the best solutions to create a stimulating, interesting environment for your animals that promotes natural behaviors.
