Our pets are part of our families, so of course we want to include them in holiday fun, but are there poisons and other dangers lurking in the cheer?

Here are some Christmas decorations to keep your fur-family away from, according to Vet Medicine on About.com.

Are Christmas trees poisonous to pets?

Christmas trees are mildly toxic. Cats especially have a difficult time resisting a little nibble on a fir tree, but the oils can irritate their mouths (causing drooling) and bellies (causing vomiting). Pine needles aren't the easiest to digest, either, so gastrointestinal obstruction or puncture are possibilities.

What other fresh tree folly can they get into?

Tree water can be full of pesticides and even aspirin (used to keep the water fresh), so cover the dish to keep your cat, dog or kids out.

Are any other holiday plants poisonous?

Poinsettia plants were once thought to be extremely toxic, but that was just an urban legend. The plant is mildly toxic and can cause vomiting, but death is not imminent.

Mistletoe and holly are considered very toxic, so if you think your pet has ingested these plants, call your vet or a poison control center immediately.

Lilies and daffodils (and other "bulb" flowers) are extremely toxic to cats and can cause cardiac arrhythmias, kidney failure, convulsions and death. Daffodils are toxic to both cats and dogs (especially the bulbs)

Any other dangerous decorations to look out for?

Christmas lights are sometimes an appealing chew toy for animals, so keep an eye on the wires (and your pets). Chewing the cords or blubs can cause shock and burns.

Holiday ornaments, if swallowed, can cause a gastrointestinal blockage or rupture.

Be careful and safe - and keep an eye on your loved ones (especially the ones covered in fur).
