Evaluation of the provision of hay to guinea pigs at GlaxoSmithKline (2006)

Cozens, M.

Abstract

Two males in the group 3 had to be euthanized due to bite wounds from fighting with cage mates - this aggression is something we have also experienced in older male guinea-pigs where it is not possible to feed hay.Male groups who received hay were less difficult to handle and they were less aggressing among each other than animals who had no access to hay.
