# Are Christmas Trees Poisonous to Cats and Dogs?

Published by Paw Multiverse (A.I.T. Multiverse Consulting Ltd) · Last updated 7 November 2026

Quick answer

Mostly an irritant, not a classic poison, but not harmless. Pet Poison Helpline says needles can irritate the mouth and stomach and, in large amounts, may block or damage the gut; tree water can cause mild vomiting and diarrhoea. Cats Protection warns that some tree oils can make cats very unwell and that swallowed tinsel can cause blockages. If your pet has eaten part of the tree or a decoration and seems unwell, phone your vet.

## Needles

Pet Poison Helpline, writing about spruce, fir and pine trees, says eaten needles can irritate the mouth and stomach and cause vomiting, diarrhoea and drooling. Because needles do not digest well, it says a large amount may cause a blockage or even a perforation of the gut. It adds that artificial trees can cause stomach irritation too, and a blockage if enough is eaten. Source: [Pet Poison Helpline, Deck the halls with holiday plants: but are they toxic?

Cats Protection advises picking up fallen needles so they do not injure cats' paws. Source: [Cats Protection, Cats and Christmas](https://www.cats.org.uk/cats-and-christmas).

## Tree water

Pet Poison Helpline says pets that drink Christmas tree water may get mild vomiting and diarrhoea, and that preservatives added to the water usually only cause mild stomach irritation. Covering the stand stops most drinking. Source: [Pet Poison Helpline, Deck the halls with holiday plants: but are they toxic?

## Cats and real trees

Cats Protection says cats are drawn to lit trees and the things hanging on them, and that some oils produced by real trees can be toxic, making a cat very unwell. It also mentions fertiliser and plant food used on trees. Source: [Cats Protection, Cats and Christmas](https://www.cats.org.uk/cats-and-christmas).

## Tinsel, baubles and lights

Cats Protection says tinsel can cause serious illness if swallowed because of the blockages it can cause, sometimes fatally; that glass baubles can shatter easily; and that cables to the tree are best covered with plastic or cardboard tubes, with the lights switched off at the mains when you go out.

## Setting the tree up

Cats Protection suggests a sturdy base, or weights, so the tree cannot topple, and keeping easily broken decorations off it. Source: [Cats Protection, Cats and Christmas](https://www.cats.org.uk/cats-and-christmas).

- Stand the tree where it cannot be climbed from a sofa or shelf.
- Cover the water in the stand.
- Sweep up needles every day, and more often as the tree dries out.
- Hang breakable and edible decorations high, or leave them off.
