No. Leeks, chives and scallions are alliums and are just as toxic to cats as onions.

Why it’s a problem

The whole Allium family — onions, garlic, leeks, chives, scallions, shallots — contains thiosulfate compounds that destroy feline red blood cells. Chives are a particular trap because they grow in gardens and garnish baked potatoes and cream cheese, looking harmless.

How to serve it safely

Keep all allium vegetables and dishes away from cats, including chive garnishes, onion dips and leek soups.

Warning signs to watch for

Vomiting, drooling and abdominal pain, then lethargy, pale gums, rapid breathing and dark urine as anemia develops over days.

When to call the vet

Contact your vet as soon as ingestion is known — delayed anemia makes "watch and wait" risky.

Common questions

Are chives dangerous in small garnish amounts?

Cats are highly sensitive, and repeated small doses still damage red blood cells. Treat any allium as off-limits.
