Drinks & misc
Can cats eat tea?
Black, green and white tea contain caffeine; tea bags and loose leaves are concentrated.
Portion: None.
The short answer
No. Black, green, white and oolong teas contain caffeine and related methylxanthines, which are toxic to cats. A lick of weak tea is unlikely to be serious, but chewing a tea bag or loose leaves is a bigger dose. Herbal teas aren't automatically safe either: some herbs are toxic to cats (for example pennyroyal), so don't offer any tea.
Why it’s dangerous
Tea contains caffeine plus smaller amounts of theophylline and theobromine, all methylxanthines. They stimulate the heart and nervous system. Dry leaves and bags are far more concentrated than a brewed cup.
How to keep your cat safe
- Don't share tea of any kind.
- Dispose of used tea bags where cats can't reach them.
- Treat herbal teas and essential-oil blends with suspicion.
Signs of trouble
- Restlessness
- Vomiting
- Rapid heart rate
- Tremors
