Why magnets are dangerous
The magnet pulls other metal objects together, creating a strong pinch inside the intestines.
A single disc can cling to another magnet or to metal fragments, crushing the bowel wall within hours.
The pet may have chewed a fridge door seal or a toy with embedded magnets, leaving a tiny shiny disc on the floor.
Why speed matters
Delaying care significantly worsens outcomes. Some signs appear hours or days later, so "looks fine right now" is not a reason to wait.
Symptoms of magnet-ingestion poisoning
- Repeated vomiting within 2‑4hours after swallowing
- Pawing at the abdomen or a hunched posture by the evening
- Diarrhoea that may contain blood after 6‑12hours
- Restlessness that turns into sudden lethargy as the blockage worsens
- The abdomen feels firm or swollen on gentle palpation
What to do right now
- Call your vet or the ASPCA Animal Poison Control Center immediately
- Do not induce vomiting because the magnet could cause more damage in the esophagus
- If you can safely retrieve the magnet, bring it with you to the vet
- Keep the pet calm and limit movement to prevent the magnet from shifting
- Transport the animal to an emergency veterinary clinic without delay
