Chervil

Chervil (Anthriscus cerefolium) is considered non-toxic to cats. It is a generally safe culinary herb, and no toxic principles have been documented for this plant in cats.

Most cats will experience no ill effects after eating chervil. In rare cases where a cat consumes a large amount, the fibrous plant material may cause mild vomiting or diarrhea that typically resolves on its own.

Small nibbles are unlikely to cause any problem. Digestive upset — if it occurs at all — is associated with large ingestions of the herb, due to the fibrous nature of the plant rather than any toxic compound.

Chervil is non-toxic, so a small amount is not an emergency. If your cat consumed a large quantity and is showing persistent vomiting or diarrhea that does not resolve within a day, contact your veterinarian.

Chervil (Anthriscus cerefolium) is non-toxic to dogs. It is classified as generally safe, and no harmful symptoms are expected from normal exposure or incidental ingestion.

Chervil is not poisonous to dogs, but large amounts of any fibrous herb can cause mild gastrointestinal irritation or loose stools. Symptoms should be minor and short-lived.

A small or moderate amount of chervil does not require a vet call. If your dog ate a very large quantity and shows persistent vomiting, diarrhea, or lethargy that does not resolve within a day, contact your veterinarian.

Chervil itself is non-toxic to dogs, so accidental exposure to a dish garnished with it is not a cause for alarm. That said, non-toxic does not mean beneficial — there is no reason to intentionally feed it to your dog, and large quantities may still cause minor digestive upset.
