Is lemon tree safe for cats and dogs?

No — lemon tree is toxic to cats and dogs and should be kept well away from pets that chew plants. 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 Citrus as toxic to cats, dogs, and horses due to citrus oils (limonene and linalool). Leaves and rind are most concentrated; the flesh is low-risk but acidic.

What to do if your pet ate lemon tree

  1. Remove any plant material from your pet's mouth and move lemon tree out of reach.
  2. Note how much was eaten and when, and watch for drooling, vomiting, or lethargy.
  3. Do not induce vomiting unless a vet or poison-control specialist instructs you to.
  4. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 and follow their advice.
  5. Bring a leaf or photo of lemon tree to the appointment so it can be treated correctly.
