Silica Gel Packets Briefly Sicken Pets
Be warned that the silica gel packets found in shoeboxes and medicine pill bottles may cause gastrointestinal problems for pets. Some symptoms found shortly right after ingesting the gel are nausea, vomiting and lack of appetite. While the silica gel is not fatal and the effects are mild, pet owners should be aware and dispose of these packets properly.
