Is Common Milkwort toxic to cats?

Polygala vulgaris

Mildly toxic to cats

Mildly. The ASPCA lists common milkwort 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. Polygala vulgaris is not individually assessed by the ASPCA. Polygala species are known to contain saponins (root bark) and methyl salicylate, which can cause mild gastrointestinal upset in cats and dogs if ingested. Classified as mildly-toxic pending specific ASPCA genus-level confirmation.

What to do if your cat ate common milkwort

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

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