Can Cats Eat Spring Onions? NZ Safety Answer
Can cats eat spring onions in NZ? No; spring onions are an Allium risk for cats.
Quick answer
No, cats should not eat spring onions. Avoid raw spring onion, cooked spring onion, garnishes, salads, stir-fries, noodles, dumplings and leftovers.
Why
ASPCA lists onion and garlic among foods pets should avoid, and Pet Poison Helpline's onion reference covers Allium food risk. In NZ meals, spring onion can be a garnish or hidden in mixed leftovers, so it is safer not to share those foods with cats.
If your cat ate it
Contact your NZ vet, after-hours emergency clinic, or SPCA for advice, especially if the food contained a known toxin or your pet seems unwell.
Safer alternatives
Cats do not need human-food variety. Safer options are complete cat food, a cat-specific treat, or a few pieces of the cat's normal food in a puzzle feeder.
