Is Black Oak toxic to cats?

Quercus velutina

Mildly toxic to cats

Mildly. The ASPCA lists black oak as mildly toxic to cats — a chewing cat typically gets mouth irritation, drooling, and vomiting rather than a medical emergency, but it is still best kept out of reach. This classification follows the ASPCA Toxic and Non-Toxic Plant List. Like all Quercus species, Black Oak acorns, leaves, and bark contain tannins and gallic acid toxic to dogs, cats, and horses if ingested in quantity. The ASPCA lists oak (Quercus spp.) as toxic to dogs, cats, and horses, causing gastrointestinal distress and potentially kidney damage with large ingestion. Fallen acorns pose the primary risk to pets.

What to do if your cat ate black oak

  1. Remove any plant material from your cat's mouth and move black oak 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 black oak to the appointment so it can be treated correctly.

General guidance, not veterinary advice. If you think your cat has eaten black oak, contact your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 — do not wait for symptoms to worsen.
