Caffeinated drinks / Soda

Caffeinated beverages — including sodas, energy drinks, tea, and coffee-based drinks — are toxic to cats because of their methylxanthine content (primarily caffeine, and in some cases theobromine). Cats metabolise these compounds far more slowly than humans, allowing dangerous levels to accumulate rapidly. Even a small amount can cause significant harm: just a few sips of energy drink can overwhelm a cat's system. Sugar-free sodas and energy drinks carry an additional risk if they contain xylitol.

Important Notes

Symptoms: Vomiting, diarrhea, and excessive thirst and urination initially; progressing to extreme agitation, rapid heart rate, rapid breathing, muscle tremors, hyperthermia, cardiac arrhythmias, and seizures.

Energy drinks are especially dangerous: They contain caffeine in concentrations far higher than soda or tea, and sometimes also taurine and other stimulants that compound the effect.

Action: Keep all caffeinated beverages out of reach. Seek veterinary care immediately if a cat has ingested any caffeinated drink.
