ALPHA-Twist™ Rolls

Unfurled ALPHA-Twist™

  • ALPHA-twist™   is comprised of twisted multi-layered paper that is chopped into short lengths. 
    Once in a cage, rodents unfurl and manipulate them into fluffy nests.

  • Maximum Environmental Enrichment:  Species specific behaviors are nurtured and enhanced through the unrolling of the material for use in nest building.  One roll of ALPHA-twist™ can be unrolled into a 5 inch strand of paper!

  • Customized Dosage:  Technicians can custom dose each cage with an exact amount of material to satisfy a particular cage or housing arrangement.

  • Economical:  One bag of ALPHA-twist™ can provide enrichment for over 1400 standard cages.  The cost per cage for exceptional enrichment is less than traditional cotton based nesting enrichment items.

  • Safer to Use:   ALPHA-twist is safer to use due to its low dust content and the absence of long cotton fiber strands eliminate strangulation issues.
