Tea Bags and Loose Tea: An Overlooked Caffeine Source

Tea bags and loose tea leaves get overlooked as a caffeine source compared to coffee, but dried tea leaves are actually fairly concentrated in caffeine relative to their volume — a pet getting into a box of tea bags or a canister of loose leaf tea is consuming something more potent than the equivalent volume of a brewed cup would suggest.

Used tea bags left in the trash or a compost bin are a common access point, since they retain a meaningful amount of caffeine and tannins even after brewing.

Symptoms to watch for: restlessness, panting, an elevated heart rate, vomiting, and in larger ingestions, tremors — essentially the same profile as coffee/caffeine toxicity generally.

What to do right now: estimate how many tea bags or how much loose tea was involved relative to your pet's size, and get an assessment if it's more than an incidental exposure (one used bag out of the trash is different from a whole box of dry bags or a canister of loose tea).

When it's an emergency: any restlessness with elevated heart rate that doesn't settle, or any ingestion of a significant quantity of dry tea (bags or loose leaf) rather than a used, already-brewed bag.
