My cat ate Dwarf Blue Lawson Cypress — what to do

Step by step

  1. Take dwarf blue lawson cypress 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 dwarf blue lawson cypress — FAQ

Is dwarf blue lawson cypress poisonous to cats?

Yes — the ASPCA lists Dwarf Blue Lawson Cypress (Chamaecyparis lawsoniana 'Minima Glauca') as mildly toxic to cats. Chamaecyparis species contain aromatic oils (including thujone-related compounds in foliage) that can cause mild gastrointestinal upset — vomiting and diarrhoea — if significant quantities of foliage are ingested by cats or dogs. The ASPCA does not list Chamaecyparis lawsoniana specifically as toxic, but ingestion should be discouraged and veterinary advice sought if a pet eats a large amount.

How serious is it if my cat ate dwarf blue lawson cypress?

Dwarf Blue Lawson Cypress 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. Chamaecyparis species contain aromatic oils (including thujone-related compounds in foliage) that can cause mild gastrointestinal upset — vomiting and diarrhoea — if significant quantities of foliage are ingested by cats or dogs. The ASPCA does not list Chamaecyparis lawsoniana specifically as toxic, but ingestion should be discouraged and veterinary advice sought if a pet eats a large amount. 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?

Keep dwarf blue lawson cypress well out of reach, or swap it for an ASPCA non-toxic plant — see the best cats-safe plants list.
