glued together with a non-toxic water-based adhesive. Which makes sense, since they are designed to contain beverages for human consumption.

the adhesives used in paper cups and paper bags are non-toxic.

These are the adhesives which adhere the parts of these items to themselves (seams).

Of course, make sure you get UN-waxed paper cups.

She said also: the boxes (or packaging) are required to state that they are wax cups. If the box just says "paper cups", they do not have wax on them. And that they will say "wax paper cups" or something like that - if they’re waxed, the labeling should say so.

She also had double checked on this with an Avian Veterinarian.

Emily is also a member of the International Association of Avian Trainers and Educators as well as the AFA, and in addition to being an avian behavior consultant and veterinary technician, she also founded the Austin Parrot Society and teaches classes about bird ownership, behavior, nutrition, basic husbandry, and a variety of other topics. Birds are pretty much her life.
