Mildly toxic to pets

Is cauliflower safe for cats and dogs?

Not entirely — cauliflower 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. Brassica oleracea isothiocyanates can cause GI upset and gas in cats and dogs in quantity.

What happens if a pet eats cauliflower?

Brassica oleracea isothiocyanates can cause GI upset and gas in cats and dogs in quantity. 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 cauliflower, treat it as a suspected ingestion and act on the steps below.

What to do if your pet ate cauliflower

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