Yes. Cat grass — usually sprouted wheat, oat, barley, or rye — is grown specifically for cats to nibble and is safe to eat. Many cats graze on it to aid digestion and hairball passage, and it gives indoor cats a healthy plant to chew instead of risky houseplants. Overeating may just cause a little vomiting.

Yes. Cat grass — usually sprouted wheat, oat, barley, or rye — is grown specifically for cats to nibble and is safe to eat.

Why this answer
Cat grass is young cereal grass raised for grazing, non-toxic and rich in fiber and moisture that can help move hair through the gut and satisfy a cat's urge to chew greenery. Unlike many houseplants it poses no poisoning risk, so it doubles as a safe outlet that steers cats away from toxic decorative plants. Eating a lot can trigger harmless regurgitation.
Watch for
Occasional vomiting of grass, which is normal grazing behavior
How much is okay
Free access to a small tray of fresh cat grass is fine; let your cat graze at its own pace and trim it back as needed.
Serve it safely
Grow it from wheat, oat, barley, or rye seed in clean soil or a hydroponic kit.
Keep the tray fresh and rinse away any mold before offering.
Place it as a safe alternative to nibbling houseplants.

Feeding Your Cat
Cornell Feline Health Center, Cornell University College of Veterinary Medicine — Feline nutrition fundamentals: cats are obligate carnivores; complete balanced cat food should be the diet base; treats should stay a small share of daily calories.

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.
