My cat chewed a used teabag I left on the counter, is this dangerous?

Short answer

Yes, this is dangerous and requires immediate action. Tea contains caffeine, which is toxic to cats and can cause vomiting, tremors, and a racing heart. Even a used teabag can hold enough caffeine to be harmful. Contact your veterinarian or the ASPCA Animal Poison Control Center at (888) 426-4435 right away.
