Brief Description: Substrates such as straw or hay are versatile enrichment items.
Materials: Fresh straw or hay
Assembly Instructions: No assembly required
How to Use: Put out large quantities of straw/hay. Fill buckets and other large containers with straw/hay and mix in forage treats so the chimpanzees must search through it. It also makes excellent nesting material and hay can be wadged at the chimpanzee’s leisure. Wood wool is another option for nesting material. It doesn’t absorb water the same way that straw or hay does so it will last longer in an enclosure
Cost: $10-$20 per bale of straw or hay. Wood wool is more expensive (~$100/bale)
