No. Beer is alcohol, and alcohol is poisonous to cats. The ethanol content is enough that a few laps from a can or glass can sicken a small cat, and beer often carries hops too, which add their own risk. There is no safe amount to share.

Why this answer
Beer delivers ethanol, which a cat's body cannot clear efficiently, so it quickly suppresses the brain, breathing, and heart. Hops used in brewing are a separate hazard linked to dangerous overheating in pets. A cat's small size means the amount in a single serving is well into the toxic range.
Watch for
Unsteady walking and disorientation
Vomiting or drooling
Lethargy or unusual sleepiness
Slowed breathing
In serious cases, tremors or collapse
How much is okay
None — beer is never a safe treat for a cat, not even a lick of foam or a splash left in a glass.
Keep it away
Do not offer beer as a joke or let a cat lap foam.
Keep open cans and pint glasses out of reach during gatherings.
Clean up spilled beer promptly so a cat cannot lick it off the floor.

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.
