Using Chewable Toys for Habitat Enrichment

It’s no secret animals want to lick, chew and taste things they find in their habitat.

This behavior comes from natural curiosity, self-comfort, and for entertainment. Chewable enrichment products are popular with animal care professionals because they’re easy to use and the animals love them. But there is growing concern about hazardous contaminants found in some plastics. A recent research paper published in Environmental Science & Technology, focused on the toxicity of everyday plastics used in consumer products.

While this area of investigation is on-going, there is an important take-away. Most of the chemicals in common plastics aren’t locked into the polymer. The chemicals can be transferred to liquids or volatize into the air. Chemicals can be ingested through the mouth and inhaled. Unfortunately, many chewable enrichment products are manufactured under questionable conditions.

Otto Environmental offers a variety of chewable toys that are manufactured in the United States.

The polymers used to manufacture the products have been evaluated by Cornel University’s Animal Health Diagnostic Center. Lab results indicate the products are free of pesticides, heavy metals and other organic compounds of concern. You can rest assured our enrichment products are safe for your animals.

The Zoy Enrichment Device is an Otto Environmental exclusive!

Made in the US, the Zoy entertains a wide range of animals. Medium to large dogs, wolves, swine, and primates are fans of the Zoy. The device has an open loop for grasping, tugging and biting. The flat section is made for chewing and can handle the most-aggressive gnawing.

Chewing and licking provides mental and tactile enrichment, but animals get bored with the same old toys. Keep chewers, like primates and dogs, happy with the Zigg.

What’s a Zigg?  The Zigg has a bumpy textured surface that satisfies the need to chew, without causing damage to teeth and gums. The polymer is chewable but can stand up the aggressive biting and gnawing. Primates especially enjoy exploring the irregular surface with their hands and mouth.

Our exclusive Z2 enrichment chew toy provides a loop handle and two chewable balls on either end.

Large primates will carry the Z2 around and use it to have a relaxing chew during a rest period. It’s also a great toy to toss around with canines.

The Zyro is a smaller enrichment product that is easily rolled, tossed, and chewed by lab and zoo animals. Lab animals such as mice, rats, hamsters, and rabbits require chewable enrichment and benefit from the Zyro. The Zyro is a comfort toy or chew device for smaller primates, small canines, and other curious animals including ferrets and rabbits.

Otto Environmental chewable products help calm animals in transport, when settling animals into an unfamiliar environment, or anytime you want to give your animals a fun, chewable toy.

Z2 Dog Toy

Z2 dog toy enrichment

The Z2 animal toy has quite a history in its evolution.  We were asked by one of our customers to come up with a colored replacement for the discontinued Nylaball.  The ball portion of the Z2 was our candidate.

After some time, it became apparent that only this customer was interested in the ball which did not justify our investment.  By adjusting the mold to attach the two balls with two center cords, a new toy resulted with the popularity one would hope for.
