Festive greenery fills homes in December — but many Christmas plants are toxic to cats. From bouquets to wreaths, know which seasonal plants to keep away from curious paws.
Lilies in holiday bouquets are lethal
Florists often add lilies to Christmas arrangements. One pollen grain can kill. Check every stem before bringing flowers indoors.
Christmas plants that can harm cats
- Lilies — fatal kidney failure. Why lilies are so dangerous
- Mistletoe — vomiting, diarrhoea, heart effects; berries most toxic
- Holly — spines plus toxic saponins; berries and leaves
- Poinsettia — mild irritation. Myth vs reality
- Amaryllis — vomiting, tremors, low blood pressure
- Christmas tree water — fertilisers, preservatives, and bacteria; keep covered
Christmas tree safety tips
Secure the tree to prevent tipping. Skip tinsel and fragile glass baubles if you have climbers. Cover the water stand — cats may drink from it. Pine needles can irritate the mouth and cause blockages if swallowed in quantity.
