My cat ate Common hollyhock — what to do

Step by step

  1. Take common hollyhock away and remove any plant material from your cat's mouth so they cannot eat more.
  2. Note roughly how much was eaten and when — this helps the vet judge the risk.
  3. Do NOT induce vomiting unless a vet or poison-control specialist tells you to.
  4. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 (a consultation fee may apply) and follow their advice.
  5. Watch for drooling, pawing at the mouth, vomiting, loss of appetite, or lethargy, and bring a leaf or photo to the appointment.

This is general guidance, not veterinary advice. Pets vary, and a reaction may be to soil, fertiliser, or pesticide as well as the plant. When in doubt, call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435.

My cat ate common hollyhock — FAQ

Is common hollyhock poisonous to cats?

Yes — the ASPCA lists Common hollyhock (Alcea rosea) as mildly toxic to cats. Alcea rosea (hollyhock) is not individually listed on the ASPCA toxic or non-toxic plant lists for cats and dogs. However, members of the Malvaceae family contain mucilaginous compounds and low levels of tannins. In dogs and cats ingestion of leaves or stems may cause mild gastrointestinal upset (vomiting, loose stools). It is not considered severely toxic, but contact dermatitis from leaf hairs has been reported in sensitive individuals. Treat with caution around pets.

How serious is it if my cat ate common hollyhock?

Common hollyhock is mildly toxic, so most cats get short-lived mouth irritation, drooling, and vomiting rather than a life-threatening reaction. It is still worth a vet call to be safe, especially if your cat ate a lot or symptoms persist.

What symptoms should I watch for?

Signs usually appear soon after chewing: drooling, pawing at the mouth, vomiting, loss of appetite, or unusual lethargy.

It is not considered severely toxic, but contact dermatitis from leaf hairs has been reported in sensitive individuals. Treat with caution around pets. Any worsening or persistent symptoms warrant an immediate vet visit.

Should I make my cat vomit?

No — do not induce vomiting unless a vet or the ASPCA Animal Poison Control Center specifically tells you to. The wrong action can make things worse. Call (888) 426-4435 and follow professional advice.

How do I stop this happening again?
