Otto Abacus (PES)


The Otto Abacus offers great enjoyment and interaction for primates.


The Abacus is a multi-sensory enrichment device that provides primates with tactile, visual, and audible stimulation. The colorful plastic shapes spin and slide on stainless-steel hardware. The bell rings when handled. All of this is mounted in a heavy-duty plastic frame. It is a popular primate enrichment product with monkeys and apes, including tamarins, capuchins, marmosets, macaques, langurs, orangutans, gibbons, and chimpanzees. Spinners is part of our Primate Enrichment System (PES). It attaches to cages and enclosures with the Universal PES Bracket. The bracket makes it easy to insert a variety of enrichment products, like the  Food and Treat Feeder and Wave Mirror. All PES components are autoclavable making it easy to maintain hygiene and IACUC standards in laboratory settings.  The Abacus is designed for animal enrichment during animal transportation, laboratory settings, veterinary enclosures, and zoo habitats.
