Is Curled Dock toxic to cats?

Rumex crispus

Toxic to cats

Yes — curled dock is toxic to cats according to the ASPCA. Keep it well away from any cat that chews plants; reactions can be significant. This classification follows the ASPCA Toxic and Non-Toxic Plant List. The ASPCA lists dock (Rumex spp.) as toxic to cats, dogs, and horses. The toxic principles are soluble calcium oxalates. Clinical signs include kidney failure (rare but reported), muscle tremors, hypersalivation, weakness, and gastrointestinal upset. Soluble oxalates bind serum calcium rapidly, causing hypocalcaemia that impairs cell membrane function. Contact a veterinarian immediately if ingestion is suspected.

What to do if your cat ate curled dock

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