No. Energy drinks are among the worst things a cat can get into. They pack concentrated caffeine plus other stimulants and often taurine and sugar, and the caffeine alone is toxic to cats at small doses. Keep cans closed and well away.

Why this answer
Energy drinks concentrate caffeine, and often guarana, which adds even more caffeine, along with other stimulants. Cats process these methylxanthines slowly, so they overdrive the heart and nervous system. The high dose in a single can makes even a modest spill a serious exposure for a small cat.
Watch for
Agitation, pacing, or hyperactivity
Racing or irregular heartbeat
Vomiting
Muscle tremors and twitching
High temperature or seizures in severe cases
How much is okay
None — energy drinks are never safe for cats in any amount, including sugar-free versions.
Keep it away
Keep energy-drink cans closed and off surfaces a cat can reach.
Clean up any spill immediately so a cat cannot lap it.
Do not leave open cans on desks or nightstands where a cat roams.

Answer card
No food checked yet.
Type what your cat is eyeing — or already stole — and the answer lands right here, without leaving the page.
Remove access. Take the food away and move your cat to another room.
Note the facts. What was it, roughly how much is missing, and when? Keep the packaging.
Call before symptoms. For chocolate, onion, garlic, grapes, raisins, alcohol, or anything sugar-free (xylitol), call a hotline or your veterinarian now — early treatment is easier and cheaper.
Never do this
Do not induce vomiting, feed milk, salt, or oil, or wait overnight to "see how it goes". Signs of chocolate or Allium poisoning can take hours to days to appear.
Go to an emergency vet immediately if
Your cat is collapsing, twitching or seizing, struggling to breathe, drooling heavily, vomiting repeatedly, or wobbly on their feet.
