September 15, 2026

Our experts at ASPCA Poison Control want to warn pet parents about severe signs following exposures to consumer migraine caps, eye masks, wraps and dog beds that contain hydrogel.

In cases of ingestion, ASPCA Poison Control has noted muscle tremors, unsteadiness on the feet, sensitivity to sound or touch and an increase in heart rate. Seizures and deaths have also been reported. Many pets will exhibit vomiting; however, that is expected when a pet ingests a non-food item.

Although the packaging may describe the product as nontoxic or medical grade, it is suspected that these products may contain acrylamide, a byproduct of manufacturing. Acrylamide, which has been detected in similar products such as water beads, is absorbed through skin, orally and through inhalation and is a potent neurotoxin for both pets and humans.

Actions to Take

If you currently let your pet use a cooling pet pad, please monitor their use of the product, especially if they tend to chew on things they should not. Additionally, keeping items not intended for pet use, such as migraine caps, eye masks and wraps, out of reach of pets can prevent potential harm.

If you suspect your pet has ingested the contents of a migraine cap, eye mask, wrap, dog bed or a cooling pet pad, please contact your veterinarian or our experts at ASPCA Poison Control at 888-426-4435. If your pet is showing neurologic signs, please take them to your closest veterinarian immediately.

At ASPCA Poison Control, our experts continue to investigate these cases and the most effective treatment.
