Signs of toxicity may include:

  • Vomiting
  • Lethargy and weakness
  • Loss of coordination
  • Tremors
  • Seizures
  • Collapse
  • Jaundice if liver damage occurs

Timeline: Hypoglycemia can develop within 30 minutes to 12 hours. Liver damage may take longer.

Can be life-threatening. Severe hypoglycemia and liver failure can be fatal.

What to Do If Your Cat Eats It
