Is parsley safe for cats and dogs?
Not entirely — parsley is mildly toxic to cats and dogs. It rarely causes serious harm, but chewing it triggers real discomfort, so it is best kept out of a pet's reach. This classification follows the ASPCA Toxic and Non-Toxic Plant List, the most widely used reference for companion-animal plant safety in the US and the standard most UK vets cite as well. ASPCA lists parsley as toxic to cats, dogs, and especially birds when eaten in large quantities, due to furanocoumarins. Culinary amounts are not a concern; concentrated essential oil or grazing on a whole plant is.
What happens if a pet eats parsley?
ASPCA lists parsley as toxic to cats, dogs, and especially birds when eaten in large quantities, due to furanocoumarins. Culinary amounts are not a concern; concentrated essential oil or grazing on a whole plant is. Signs usually appear soon after chewing rather than hours later. If you see drooling, pawing at the mouth, head-shaking, vomiting, loss of appetite, or unusual lethargy after your pet has had access to parsley, treat it as a suspected ingestion and act on the steps below.
What to do if your pet ate parsley
- Remove any plant material from your pet's mouth and move parsley out of reach.
- Note how much was eaten and when, and watch for drooling, vomiting, or lethargy.
- Do not induce vomiting unless a vet or poison-control specialist instructs you to.
- Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 and follow their advice.
- Bring a leaf or photo of parsley to the appointment so it can be treated correctly.
