Yes. Plain blueberries are a safe occasional treat for cats. They are non-toxic, low in sugar for a fruit, and their antioxidants and water do no harm in small amounts. A cat may or may not care for them, and a couple of berries is plenty.

Why this answer
Blueberries contain no compounds toxic to cats, and their fiber and antioxidants pass through without trouble at treat-size amounts. Cats are obligate carnivores, though, so fruit sugar and carbohydrate offer them little nutritional value and should stay a tiny share of the day's calories.
Watch for
Loose stool or mild stomach upset if a cat eats a large handful
Fussiness at the next meal if berries spoil the appetite
How much is okay
Two or three berries, once or twice a week, fresh or thawed and cut in half for a small cat — never a daily bowlful.
Serve it safely
Wash the berries and serve them plain, with no yogurt, syrup, or sweetener.
Halve or mash them for a small cat or kitten to avoid a whole berry going down fast.
Skip muffins, pie filling, and dried blends, which add sugar and sometimes xylitol.

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.
