Why?
An energy drink packs a lot of caffeine, often boosted with guarana, another source of caffeine. For an animal that weighs a few pounds, a few laps can be enough to overstimulate the heart and nervous system. Add plenty of sugar or sweeteners on top. The taurine they contain doesn't make up for anything: cats already get it from their food.
How much?
No amount is safe. Never leave an open can within reach, even an almost empty one.
The risks
- Severe restlessness, panting
- Very fast or irregular heartbeat
- Vomiting
- Tremors and seizures
- Rising body temperature
Your cat ate some: what now?
Call your vet or an animal poison control center right away, without waiting for symptoms: these drinks are far more concentrated in caffeine than soda. Keep the can to show the ingredients and estimate how much was drunk. Don't try to make your cat vomit.
Better options
Fresh water is the only drink your cat needs. For an energy boost, nothing beats a play session with a feather wand.
Common questions
Energy drinks contain taurine, isn't that good for cats?
Taurine is essential for cats, but they get it from cat food and meat. In an energy drink, what matters is the caffeine, and that's dangerous for them.
My cat licked an energy drink can, what should I do?
Call your vet for advice, even if your cat seems fine: the caffeine is very concentrated. Watch for restlessness, panting, vomiting and tremors over the next few hours.
