Scallion

Cats are more sensitive to Allium plants, and even very small amounts may cause oxidative red cell damage and anaemia.

n-propyl disulfide and related organosulfur compounds

Drooling, vomiting, lethargy, pale gums, weakness.

Seek veterinary care promptly and record how much was eaten and when.

Cats chewing kitchen scallion tops is not unusual - keep chopped onions out of reach.

Scallions contain the same organosulfur compounds as onion, and both the white base and the green tops are risky; repeated small amounts can accumulate and cause anaemia, with a higher risk for small pets.

n-propyl disulfide and related organosulfur compounds

Vomiting, diarrhoea, drooling, lethargy, pale gums, rapid breathing, dark urine.

Stop feeding and contact a veterinarian, stating whether tops or bulbs were eaten and roughly how much; signs can be delayed for days, so assessment within 48 hours is still recommended.

Common exposures: spring onion omelettes, cold dressed dishes, noodle soup garnish, barbecue dips and savoury fillings; raw vegetables are not automatically harmless snacks.
