Poinsettia can be listed as toxic but it is a low toxicity plant. Your pet can be affected either by contact or by consumption. If your pet has regular contact with the poinsettia symptoms such as eye irritation, conjunctivitis and eye ulceration can be seen. Skin disorders such as dermatitis, skin irritation and blisters can also become evident. If ingested it can cause nausea, vomiting, diarrhoea and abdominal pain. Even though it can cause problems in your pet, it is a low toxicity plant as the symptoms are usually quite mild in the sense they can not cause organ damage or death (although they can still be quite distressing).
