Can Cats Eat Chives? NZ Safety Answer
Can cats eat chives in NZ? No. Chives are members of the toxic Allium family. Even tiny amounts damage red blood cells and trigger hemolytic anemia.
Quick answer
No. Cats should not eat chives. Chives are members of the *Allium* family and are highly toxic to cats, causing Heinz body haemolytic anaemia.
Why
Chives (*Allium schoenoprasum*), whether fresh, dried, or cooked, are extremely dangerous for cats. As members of the *Allium* genus, they contain organosulfur compounds that cause oxidative damage to the cat's red blood cells. Cats are exceptionally sensitive to allium poisoning compared to other animals. The toxic compounds cause the haemoglobin in the red blood cells to clump together, forming Heinz bodies. This makes the red blood cells fragile, causing them to rupture and be destroyed by the body (haemolytic anaemia). This leads to a severe decrease in the oxygen-carrying capacity of the blood. Symptoms can appear from a single ingestion of chives or from small, repeated ingestions over several days.
How much is a problem
Cats are highly sensitive, and there is no safe dose of chives. A tiny sprig of chives, or human food garnished with chives (like sour cream and chives, or seasoned potatoes), is enough to trigger toxic red blood cell destruction.
If your cat has eaten it
If your cat has consumed chives, do not wait for symptoms to show, as Heinz body anaemia can take 12 hours to 5 days to develop. Monitor them for signs of allium poisoning: pale, mud-coloured, or yellowish gums, lethargy, muscle weakness, rapid breathing or panting, rapid heart rate, and dark orange or red-coloured urine. Gastrointestinal irritation (vomiting, diarrhea, drooling) can also occur.
Safer alternatives
Cats do not need herbs or vegetables. Keep fresh chives out of reach, and offer only cat-safe grass (such as cat grass) if your cat enjoys chewing on green plants.
