Frequently Asked Questions
Frequently Asked Questions
Are silica gel packets really toxic?
The silica itself (silicon dioxide) is essentially non-toxic and the "Do Not Eat" warning is mainly about the packet being a choking and blockage hazard. Ingested beads usually cause only mild stomach upset. The rare concern is a moisture indicator that contains cobalt chloride, which is mildly harmful.
What if my pet swallowed the whole packet?
The bigger risk is physical, not chemical. An intact packet can block the throat or intestines, especially in small dogs and cats. Do not induce vomiting — that could lodge it in the throat. Call a vet, and watch for vomiting, not eating, belly pain, or constipation.
Do I need to do anything if my dog just chewed a packet open?
Usually not much beyond monitoring. Wipe any beads from the mouth, offer water, and watch appetite and stool for a day. Call a vet or poison hotline to be sure, especially if your dog vomits, seems lethargic, or ate a large amount of beads.
