Is Boxwood Toxic to Cats?
Also known as: Common Box, European Box · Buxus sempervirens
What makes it toxic
Steroidal alkaloids such as buxin and buxine, plus volatile oils in the leaves and stems. They irritate the gut and in larger amounts affect the nervous system.
Warning signs to watch for
Drooling, vomiting, diarrhea and loss of appetite within hours. Significant ingestions can add staggering, tremors and breathing difficulty.
What to do if your cat eats it
Remove plant material, offer water and monitor. Call your vet if vomiting persists or any wobbliness appears; emergency care is needed for tremors or trouble breathing.
Common questions
Is boxwood toxic as a hedge or only when cut?
Living hedges and clippings are equally toxic. Fresh trimmings left on the lawn are especially easy for cats and dogs to chew.
Are boxwood wreaths dangerous to cats?
Yes. Dried or fresh boxwood in decor still contains the alkaloids. Keep arrangements out of reach or choose a pet-safe greenery alternative.
