Tea contains caffeine and, in some sources, theophylline — both methylxanthines in the same chemical class as the theobromine found in chocolate. These compounds block adenosine receptors, causing CNS stimulation, a faster heart rate, and increased urination. As with coffee and chocolate, cats are considered more sensitive to methylxanthines than people.
No cat-specific amount was found. ASPCA lists caffeine as a hazard to pets. Contact a veterinarian after any meaningful ingestion of tea leaves or tea products.
It is best avoided. Decaf still contains some caffeine, and some herbal teas contain herbs and oils that are unsuitable for cats.
Remove it, check how much was eaten, and contact a veterinarian or pet poison hotline, especially if it was caffeinated or the string and staple were swallowed.

Pet Poison Helpline states its service covers the U.S., Canada and the Caribbean. The ASPCA line is also used by Canadian pet owners. A consultation fee may apply to both. In Canada, your nearest 24-hour emergency vet clinic is the best first call; elsewhere, use local emergency veterinary directories.
How we calculate results: This tool uses commonly referenced veterinary toxicity thresholds and food safety guidelines. Actual toxicity can vary based on your pet's size, health status, and exact substance consumed. These results are estimates only and do not replace a veterinary assessment.
