Title: Vertebrate Animal Cage Divider


Invention: This technology is a means of separating small caged research animals, such as mice, to help reduce aggression and injury.


Background: Mice fight for a multitude of reasons, whether it be for dominance, resources, territory, breeding, or aberrant behavior. Some animal models used for research, such as mice with traumatic brain injury, are more likely to be aggressive. Data indicates that the presence of a cage divider reduces aggression among laboratory animals, thereby improving animal welfare. This technology provides a solution to the common behavioral problems that often occur with mice, such as aggression.



  • Research
  • Commercial (ex. animal care facilities and pet owners)



  • Helps to reduce aggression in laboratory animals
  • Applicable to in-home use for customers who want to have more than one mouse/rat as a pet
  • Reduce maintenance costs
  • Improves research by reducing the likelihood of animal models becoming injured
  • Applicable to animal cages in research facilities as an alternative to current methods of division and separation
  • Does not interfere with an animal’s ability to obtain food or water
  • Does not interfere with a researcher’s need to observe and/or care for the animal
