Abstract

Each blanket costs approximately $0.40, allowing us to purchase large quantities at low prices. Blankets are disposed of every other day, and a new clean blanket, often one that provides different colors, shapes, and patterns than the one before, is given to provide even more sensory stimulation for the primates.
