Questions about Snapdragon

Are snapdragons toxic to cats?

Snapdragons (Antirrhinum majus) are considered non-toxic to cats. They are generally regarded as safe, though non-toxic does not mean harmless in large quantities.

What happens if my cat eats a snapdragon?

Eating a small amount of snapdragon is unlikely to cause any problem. If your cat consumes a large quantity of the fibrous plant material, mild vomiting or diarrhea may result from the bulk alone, not from any toxic compound.

How much snapdragon is dangerous for a cat?

No toxic threshold exists for snapdragons because they contain no documented toxin for cats. The only concern is gastrointestinal upset from eating a large volume of plant material, so occasional nibbling carries very low risk.

Should I call the vet if my cat ate snapdragons?

Monitor your cat for vomiting or diarrhea; most cats will show no symptoms at all. If your cat ate a large amount and is showing signs of distress, contact your veterinarian — or the ASPCA Animal Poison Control Center at (888) 426-4435 — to be safe.

Are snapdragons toxic to dogs?

Snapdragons (Antirrhinum majus) are considered non-toxic to dogs. They are classified as generally safe, meaning no toxic principles are known that would cause poisoning in dogs.

What happens if my dog eats snapdragon flowers or leaves?

No symptoms are expected from a small amount. If your dog consumes a large quantity of the fibrous plant material, mild vomiting or diarrhea is possible due to digestive upset, not toxicity.

What should I do if my dog ate a snapdragon plant?

Monitor your dog for signs of mild GI upset such as vomiting or diarrhea, which can occur after eating large amounts of any fibrous plant material. If your dog seems distressed or symptoms persist, contact your veterinarian.

Does the quantity of snapdragon eaten matter for dogs?

Yes — a small nibble is very unlikely to cause any issue, but eating a large amount of plant material can lead to mild vomiting or diarrhea from the bulk and fiber content alone, not from any toxic compound in the plant.
