Candy and other sweet foods – especially those containing poisonous xylitol like jellybeans, puffy marshmallow chicks, and candied eggs — can also be poisonous to pets. Large ingestions of sugary, high-fat candy and sweets can lead to pancreatitis in pets. Potentially fatal, pancreatitis is inflammation of the pancreas and very painful. Pet owners should be aware that clinical signs of pancreatitis may not present for several days after ingestion. Signs include a decreased appetite, vomiting, diarrhea, lethargy, abdominal pain, and potentially, kidney or organ damage.
When pets get into candy, they can eat the wrappers too. Ingestion of foil and cellophane wrappers can sometimes cause a life-threatening bowel obstruction, which may require surgery to correct. Watch for vomiting, decreased appetite, not defecating, straining to defecate, or lethargy. X-rays or even ultrasound may be necessary to diagnose this problem.
