Colorful, plastic glow-in-the-dark jewelry, such as necklaces, bracelets and hand-held glow sticks, are not usually harmful, Kathy. While the luminescent liquid inside these products might look as though it could be poisonous, the relatively small quantity of fluid generally has a low potential for toxicity.
This oily, glowing substance is called dibutyl phthalate, and can be found in a wide variety of products, from plastics to insect repellents. Based on our experience, most animals who have chewed on glow jewelry have exhibited signs such as profuse drooling, hyperactivity, agitation and/or aggressive behavior. However, while these effects may seem serious and quite alarming to pet owners, they are typically transient, lasting only a few minutes, and are only a response to the liquid’s unpleasant taste. Generally, the only treatment needed is diluting the residue of taste by giving your pet a small amount of milk, tuna juice or soft pet food. If the residue is on the animal’s skin or hair coat, mild soap and water can be used to wash it off?and you’ll avoid the possibility of further ingestion when the animal grooms himself.
