Are Christmas Holly Plants Poisonous to Cats?

I have lots of holly around the house for Christmas. My cat is really interested in the red berries. Are the berries poisonous to my cat if she eats them??

Hi Laurie,

The red berries of Holly plants, which are very appealing to cats, are poisonous. If your cat eats these attractive red berries, he may experience vomiting and diarrhea. You should contact your vet immediately if this occurs.
