Is there anything nicer than decking the halls at this time of year, tying boughs of holly and ivy to the staircase and pinning mistletoe hopefully in every doorway?

It is vital to take precautions to ensure they are not nibbled on by hungry puppies and curious cats. And if any of them do start showing symptoms that indicate they’ve eaten Christmas food that is dangerous for pets, be ready to contact the vet immediately.

1. Poinsettia

We’ve got a seasonal soft spot for every nana's favorite – the traditional, if tricky to care for, poinsettia. They are famous for their cheerful scarlet leaves, but these red petals contain a milky white sap which contains a chemical that can cause nausea, vomiting, drooling and diarrhoea, and also irritation in the skin, mouth and oesophagus.

2. Holly

If the berries or spiked-edge leaves from a holly plant are ingested, this can irritate their mouths, lead to drooling, vomiting and diarrhoea. It may also cause excessive head-shaking if consumed in large quantities.

3. Mistletoe

The iconic white berries of mistletoe contain chemicals including polysaccharides, alkaloids, and lectins which are harmful to both dogs and cats. When ingested in small quantities, it can cause vomiting and abdominal pain. Consumed in large quantities, it may cause abnormal heart rate, low blood pressure and incoordination or ataxia.

4. Yew

Yew boughs have been used for festive decorations for centuries. But all parts of this plant, (including the leaves and berries) are highly poisonous as they contain taxines. When ingested they can cause vomiting, weakness, breathing difficulties and in critical cases, life-threatening changes in heart rate and blood pressure.

5. Christmas trees

If the pine needles from trees are chewed, the oils released may cause irritation in the mouth as well as stomach upset. Due to the prickly nature of the needles, these could also be hazardous to the mouth, throat and stomach if ingested.

6. Ivy (Hedera species)

The ivy wreathed round bannisters or across tables and mantlepieces can cause severe skin irritation if pets come into direct contact with this plant. If ingested, ivy can also cause stomach upsets.

7. Amaryllis

These make a great gift for plant lovers, but the whole amaryllis plant contains toxic substances. The higher quantities are contained in the bulb, so be careful of pets who like to dig. If eaten they can lead to vomiting and abdominal pain, loss of appetite, lethargy and tremors.

8. Lillies

Beautiful to look at and to smell, but extremely dangerous to both cats and dogs, if any part of a lily is swallowed, even in small quantities, this could cause severe gastrointestinal damage, which may lead to kidney failure for cats.

9. Laurel

Bay laurels are safe for humans to use in cooking and often used to flavor food, but this and cherry laurel, contain toxins located in all parts of the shrub which cause vomiting, abdominal pain, hypotension and in extreme cases, muscle weakness and even seizures in animals.

10. Snowdrops

These delicate white flowers are the first sign that winter is ending and spring is coming. However, as fragile as and innocent as they may seem, they contain toxins in their stems and leaves, with the highest concentration in the bulb. If ingested, they can cause abdominal pain, vomiting, incoordination as well as a drop in heart rate and blood pressure.

If you still want to include traditional Christmas decor in your home for the holidays, Salman Haqqi, the pet insurance expert from money.co.uk, says it is possible – but be aware of the dangers!

'Pets are often curious creatures and can be found chewing anything around the house, especially at a young age. While decorative plants can add a bit of a life to your interior during winter, it’s important to remember that these could present problems if consumed by your furry family members.'

'Placing plants out of reach or adding barriers to ensure pets don’t come into contact with them will help to ensure that pets do not ingest them. If your four-legged friend does consume a toxic house plant, it’s important to seek expert help and advice from your vet as soon as possible.’

But for a full on festive display that will keep your pets safe, go for faux Christmas plants and alternative Christmas trees. There are lots of realistic artificial options out there which your pet can be around without fear of doing them harm. Plus, you can reuse them year after year. And if you are gifting greenery to people you know have animals, be sure to choose varieties that are pet friendly.
